Seeing as how this has mastery rating on it, does anybody yet know if this will be an arms only talent buff?

Cast time is listed as instant which gives the implication of being a spell but it has no rage cost or cooldown listed which implies that it is a passive.

My guess is that it is an all-warrior passive that arms warriors may benefit even further from.

I have broken down all of the current masteries into two categories: unique, interesting masteries and flat bonus masteries.

Unique, interesting masteries:

Flat bonus masteries:

Why this mastery is interesting
This is essentially elemental overload for arms warriors. Seeing as arms warriors have make huge, slow attacks, having a chance to deal 50% more damage on an already devastating weapon swing sounds very good. If this mastery works with abilities like mortal strike, and not just weapon swings, this mastery becomes even more attractive.

Not sure if there will be an ICD but then there might be a "cap" for Mastery rating once lvl 85.

EDIT: It does't seem to have an ICD, it's been buffed from 50% dmg to 75% and it doesn't give any rage.

How much mastery is need for one point in mastery?

I cant sleep, so i thought i would do some theory crafting:

Im going to preface this by saying that I dont have a high level warrior, and I haven't used log data to work this out.

40% crit is a 40% chance to deal 200% damage, 40% SoO is a 40% chance to deal 100% + 115% of your average white hit, for auto attacks this is simply 215%.

Here is where this get interesting: Due to deep wounds a critical strike will also add 48% of your average white hit damage, people tell me deep wounds is usually between 23% 25% of a warriors total dps.

White hits are almost always 20% of your dps.
which leaves roughly 55% of your dmg coming from your abilities.
Lets assume on average your abilities hit for 150% of average white hit.

In this case a SoO proc only adds 76.7% to the ability's damage however since (please correct me if im wrong) SoO doesnt crit for a warrior with 40% chance to crit, this is reduced to 54.8% of the ability's average damage

So putting all these assumotions together here is the damage break down:
White + SoO = 23.3% (16.5% boost)
Ability + SoO = 71.6% (30.1% boost) (this messed with my head for ages, basically what it says is since you do 2.75* as much damage for an average damage of only 1.5* per hit, you hit ALOT more times with abilities than white hits, which makes perfect sense)
Deep wounds = 25% (0 boost)

Now you can use these values straight off, to simulate the bonus you would get if you had capped it at 100% chance to proc, namely 19.9% extra damage or you can evaluate what one extra point of mastery gets you +0.46% damage
Even if you assume that your crit chance is 10% this only goes up to 25% extra damage and 0.58% per mastery rating, so unless im missing something crit chance is outstripping mastery by a whopping 0.90% extra damage per % crit.
Not so masterful?

Much better than combat rogues Main Gauche in every way...

Strikes of Opportunity can crit

There is alot of debate amongst pvp warriors whether mastery > crit, or crit > mastery.

Mastery:
procs can crit
less diminishing returms or softcap
1 mastery for 2% proc

Crit:
increases valuability as mastery and strength increases
diminishing returns at high crit levels
1 mastery for 1% proc

The answer is probably somewhere in between. Dependent on your gear level and itemization. You want enough strength to make your crits count, and you want enough mastery to make you crit more often. And you want enough crit to make your procs and normal hits hit hard. As you get more mastery/strength, crit becomes more valuable. And as you get more crit, it becomes less valuable.

But you hands down want more mastery than crit. SoO procs sudden death, allowing for more CSs which are currently our best ability. In addition, it's cheaper. 8% of itemized crit...will get you 16% of itemized SoO. In addition, it's diminishing returns are half that of crit, because it's hit can crit itself.

SoO's stat value is 2% for every 1 mastery, and it costs as much as crit (1 mastery (2% soo) = 1% crit). It is just over 4x as valuable as crit. Thus, I will try to get my mastery and crit at a 4:1 ratio. I.e. right now my crit is 8%, so I want 32% mastery. If you look at the itemization of our gear and talents, it's as if blizzard wants us to be at this ratio. When I hit 85 I had 26% mastery and 6% crit.

Obviously this estimation doesn't account for deep wounds, and the 115% dmg of Soo, sudden death, cs, and the +crit chance to overpower, mortal strike, and heroic strike. That's unnecessary math to me, but anyone feel welcome to do it.

When you add in all the talents we have to crit, +55% to overpower, +10% to mortal strike, +15% to heroic strike (with incite), mastery becomes even more valuable.

Finding a ratio for strength to crit/mastery would be a good idea. But that one is a much tougher egg to crack, maybe I'll figure that out and post it later. When I finish grinding honor and start really caring about my gems/reforges.

Edit: more testing, and even rend procs SoO.

Comment by overon

does it procs with bladestorm and other abilities?

Comment by Carusun

Can a SoO hit proc another SoO hit?

Comment by 660647

I don't know, but if smb managed to stack mastery to 100%, and this could proc off of it self, wouldn't that make a huge, I mean HUUUUUGEEEEE doom for any1, as... Imagine:
You are Arms warrior, equiped with... say-- Well-Worn Bat and with 100% of chance to proc this. You go to Deathwing, make a swing, and it proces aditional swing. Because it can proc off of the aditional swing, it proces over and over again, making the whole server lagg, disconect countless of ppl and literely one-shot Deathwing. It wouldn't be a geometrical DPS progresion, it would be a One-shot fest

TL;DR - No, it can't proc off of itself. And I say that while not even being in Cata -_-

Comment by 660647

And then the very first swing turns out to be a miss ^^

I believe you aren't that dumb to not be hitcapped, are you?

Talking about misses, can the procced swing be a miss, if you are not hitcapped for whatever reason?

Comment by 660647

hit cap is for yellow hits

Lol, Rogues do 30-60% of their damage through white hits, and +hit really increases their damage on bosses more than, say, crit until they reach white hit-cap, at which point, hit does nothing at all.

Another example for you - TG warriors. Their Precision will now increase auto-attack (aka white) damage by 40%. 40%. Darn, that will make white hit-cap even more desirable for them, as their auto-attacks will do, well, huge damage. So yes, there is white hit-cap and it is very important for some ppl.

Comment by 615382

What white hit caps and yellow hit caps are you talking about? This is Arms spell. White hit acp=Yellow hit cap=8%
It is not equal only for duals.

Comment by 660647

Yeah, but comment that hit cap is only for yellows is too ridiculious to not get laughed at

Comment by 762431

funny thing is, it can proc from heroic leap.

check this out.

Comment by Hairband

What does Strikes of Opportunity really mean? Everyone writing here thinks they understand it, but I want to make sure we are all understanding one another.

Strikes of Opportunity grants a 17.6% chance for your "melee attacks" (however that's defined) to instantly trigger an "additional" (as in equivalent, identical?) melee attack for 100% "normal" damage (as in for the equivalent amount of damage, either a finite number or a range, or "normal" damage?). Each point of Mastery increases this chance by 2.2%.

So I hit MS and Rend. Are those are both "melee attacks," or does melee attack only mean an ordinary white auto-swing? It doesn't for sure say in the definition but Summerz and Konate above indicates yes, Strikes of Opportunity does work on your yellow damage spells and talented abilities as well.

Say that Blizz means any melee attack, including my baddest yellow damage. So my MS initially hits for say, 500 and my Rend hits for say, 500 initially and maybe 250 for 15 more seconds. (Just pulling out numbers from the air for sake of making my point--I realize some numbers are fixed and some are weapon damage numbers including a range of numbers.)

So Strikes of Opportunity can proc a second, bonus, MS for 500 (an additional melee attack for normal damage)? And likewise, Strikes of Opportunity can proc a second, bonus Rend for either the 500 initially, or for that matter, for the 250 sometime during the 15 minute DOT thereafter?

I am really, really curious what some data would look like, showing standard DPS rotation on a boss and see what procs Strikes of Opportunity and really see it in action. Odds are, that you will get an additional tick on Rend attributable to Strikes of Opportunity, even if you have 0 points in mastery.

to instantly trigger an "additional" (as in equivalent, identical?)

100% "normal" damage (as in for the equivalent amount of damage, either a finite number or a range, or "normal" damage?)

Not really, additional just means "another" attack. It doesn't have to be the same, it can be less, more, completely different, as long as it is another attack then it's an additional attack, it doesn't have to be equivalent.

As for "100% normal damage" to my mind that would be a standard white melee swing, not a copy of the exact damage done by the ability that triggered the proc. As for procs from DoTs, well I should think not. If you apply rend, then run out of melee range you couldn't, in theory, get a free swing with your weapon. So I should think that only actual hits would count.

My Summary (only my humble opinion or course) : Any time you hit with a melee strike (be that white auto's, specials, talents etc. etc.) you have a X% chance to use that "opportunity" to gain a free standard "strike" for 100% of your weapon damage.

Comment by Craz

If a proc could proc another, then blizz would 100% without question make a cooldown on it. Just as Sword Specialization was in TBC, I believe it had 5% chance to proc another attack, with like a 6 sec hidden cooldown to prevent this exactly.

I use to play arena as sword spec with a shaman partner (wf totem when it use to give an extra weapon swing). I once instantly killed a mage in arena with auto attack + mortal strike + sword spec proc + wf proc all 4 landed exactly at the same time.

Blizzard learned their lesson with reckoning bomb in classic.

Comment by WTBaggrodump

The thing that I wonder is, if you can stack Deep Wounds as per normal with your crits should you get a crit in before it finishes ticking, thus building it up higher and higher and higher... Could this mastery talent, which has a chance to proc an instant 100% dmg white hit, help it build up even faster? Should that "free" hit crit, it'll apply another Deep Wounds stack. Therefore this is more epic than one would expect! Sexy times, yes? :0

Comment by 634946

Just gunna go ahead and say what everyone wants to say but won't. This mastery sucks monkey balls.

Comment by 419043

Will this proc from abilities like Bladestorm(yellow damage) or just from melee weapon swing(white damage) ?

To answer my own question...

1. It proc from both abilities(yellow damage) and melee weapon swing(white damage)
and It can crit..

Comment by 916355

This is the best mastery ever. This maked me like arms much more... i prefer mastery before crit in pvp also.

Comment by 585305

So, I have an interesting question. While using an AoE-Arms build (take two points out of Incite and place in Thunderclap), I noticed that Thunderclap can proc this Mastery at times. That much I understand, as it was stated that most if not all Warrior abilities count as melee hits, even if they aren't necessarily such.

What I'm wondering is... Is there a limit to how many targets it can proc on? I haven't had much time, or really any easy way to extensively test this, but from what I've noticed, each 'clap only seems to proc against one target. I haven't had it proc on two different targets despite it coming from a multi-target damaging ability.

I ask mainly because I know the Marksman Hunter's "Wild Quiver" does that with Multi Shot; It can and will proc against more than one of the targets that it hits. If it's the same for SoO, I might start looking into stacking it a little more, but if it's capped to "Once per attack" then I'll likely leave it as is.
