No.

Next major content patch extra attacks will no longer be able to proc other extra attacks. So their really isn't a point in calculating for it.

But all the attack information is in WWS (sniped from someone else's public log)...

5315 melee hits, 2658 of which were MH, 728 of which were WF. 1205 SS hits. So 38.4% of WF-possible attacks are SS, and you'd figure given a perfect sample that would translate to 151 less WF procs. So now you're down to 448 WF procs. If you assume WF damage is equal to melee damage to simplify (it's not, hence this is an underestimation) that means about 8.4% melee damage. Given 66% of damage is melee, that's a little under 5.6% total loss for this sword rogue.

I'm not sure how much WF skews the average melee attack damage, however.

Edit: when using tabs to format, don't forget if your tab settings aren't standard :/
Edit2: Changed math, assumed half of melee attacks are OH.

Thanks Malan + Klixx sorry for the slight OT.

So my analysis shows from 296 attacks that could previously proc WF, I would lose 134 of them, that's 45% of my WF attacks.

Edit: These numbers are taken from my own log of Magtheridon last night. 690 melee attacks, 130 SS, 4 eviscerates, 74 windfury procs. 2.7 speed mainhand, 1.4 speed offhand.

Wrong reply by me. Drunk coffee. Redone maths. Apologies to all. Move on, nothing to read here.

I noticed the post was in the wrong thread too. I'm not convinced that this is the best fix for WF totem either.

Unless they change it majorly, WF totem is still going to be the best choice for a melee group with good enough gear, simply because it scales with weapon damage and none of the other options do.

As it works through a temporary weapon buff on the main weapon, it has a number of nasty features which means its a bit of an ugly thing.
a) it doesn't work on Offhand weapons, given more of an advantage to 2H weapons, b) shaman have a better option in windfury totem, c) it doesn't work for feral druids or hunters (both of which it arguably should work for), d) it's better than poisons which minimises a rogue class feature. e) it used to work with special attacks, which is the one thing they seem intent on removing. f) it's markedly better than using other weapon buff totems. So no fire totem is typically dropped.

One solution would be to make it a passive haste aura.

Apologies Pewsey, I was using my own data. I have now edited my above post. I think you're overestimating the number of attacks which can proc WF by including offhand attacks in your 797.

From the standpoint of a warrior, even with various haste procs, my average mainhand speed is still slower than 1.5, so this change is going to remove roughly 50% of my windfury procs while spamstringing. Unfortunately I don't have any good WWS's on hand to really parse(Damn shortage of shamans).

Another thing to consider is that Windfury totem provides a short, but certainly significant, boost to AP right after a proc, so damage loss is going to be even higher than simply lost damage from missing procs and lowered rage generation. I haven't nailed down the exact duration of the AP buff, so I can't exactly quantify how much DPS fewer procs will cost in lost AP.

Well I'm still putting out a reasonable amount of DPS without hamstring spam, but my 33/28 Warrior dropped way way way down on the charts, and the 20/41 2-hand Fury Warrior isn't much better.

Yeah, you weren't the only one to make this mistake I still need to do my daggers over again too.

MS/Slam analysis

Just a quick bit of math. Data taken from Bigdumbcow's WWS of a recent Mag kill. He's a PvE/PvP hybrid MS/Slam build.

Taking average white damage as Windfury damage, this will skew the numbers a bit, but it's easier to calculate. This also implies that we assume extra attacks awarded by Windfury can glance, I'm not sure whether they can or not.

36% crit rate for "Melee" hits, average hit of 898, average crit of 1957. Total average "Melee" hit = (898 * 0.64) + (1957 + 0.36) = 1279

73 total Windfury procs

[edit1 because WF can't proc itself]

# of eligible Windfury proccing hits
Total "Melee" hits + crits: 116 + 74 = 190 (this includes attacks awarded by WF)
Removing WF procs after finding out WF can't proc off itself:
190 - 73 = 117
MS hits + crits: 38 + 23 = 61
Slam hits + crits: 29 + 14 = 43
WW hits + crits: 21 + 16 = 37
Execute hits + crits: 2 + 1 = 3
HS hits + crits: 7 + 1 = 8
Revenge hits + crits: 3 + 1 = 4
VR hits + crits: 1 + 0 = 1
Hamstring hits + crits: 6 + 2 = 8

Not sure if Decapitator, Thunder Clap or Shield Bash can proc WF, ignoring them for now since the effect of including/ignoring them will be minimal anyway.

Total # of eligible Windfury proccing hits ~= 282
Observed WF proc rate: 73 / 282 = 25.89%

The # of eligible Windfury proccing hits goes down from 282 to 125 ("Melee" - WF + HS), new number of WF procs based on observed proc rate ~= 32

Losing 73 - 32 = 41 WF procs, at an average damage of 1279 is a "Melee" damage loss of 1279 * 41 = 52,439 damage

Total combat time was 584 seconds, 94% presence puts his combat time at ~549 seconds. Total damage dealt as it stands: 514,167 which gives a DPS of 514,167/549 ~= 937 DPS, this is close enough to what WWS calculated, rounding errors I assume.

With the hotfix in place, and a loss of 52,439 damage due to WF not proccing on specials minus Heroic Strike, total damage dealt = 514,167 - 52,439 = 461728, which gives a new DPS of 461728/549 ~= 841 dps

That's a loss of ~96 dps
or a 52,439 / 514,167 = 10.20% reduction in damage output

These numbers underestimate the dps loss due to a few reasons:

Average Windfury damage will be higher than average white damage due to the Attack Power bonuses. Also I'm not sure if Windfury procs can glance, if they can't, then again, the dps loss will be greater than calculated. [edit1: It seems WF procs can glance, so only the former reason applies]

The other glaring area where I can see a potential problem in my calculations is:

I think WF can proc off itself. The 198 is "Melee" hits + Heroic Strike, but the 190 original "Melee" attacks include the 73 WF procs. So the new number of WF procs could potentially be lower than 198 * 0.2056 = 41, but I'm not sure how to fix that.

Please analyse and correct as necessary.

[edit1]: Changing it so WF can't proc off itself changed the dps loss from ~75 dps to ~96 dps. Please re-review.

where are you looking to get a breakdown of how many SS/MH/OH attacks were made? Not finding that.

I am really trying to refrain from any uneducated whines, however, I can only see this as being a huge blow to both Arms warrior DPS and the already aenimic ret paladin DPS.

The arms warrior hit is substantial for my guild personally, because we rely on one to provide blood frenzy and put out competitive DPS numbers himself..The combined loss of his DPS, and the DPS of the rogues, is going to hurt.

As a guild that just recently downed Vashj, and having to overcome to the absolute ridiculous DPS requirements of that fight, I am a little worried.

SS is listed right there, MH/OH you can only estimate given total Melee - WF procs. At this point, though, I've found more holes in my math than I really care for (latest one was forgetting how significantly different MH and OH speeds are for swords) and am just gonna wait out the new logs.

Windfury totem has no cooldown, so your weapon speed doesn't matter.

You just add the normal and crits lines then? Or is it just landed? They have their crap setup in a weird way.

Nvm, i got it all figured out.

oddly enough your math and WWS's SS% is the same. ... wait didn't figure MH/OH attacks. ugh... im not even gonna do it now

... so i decided to do it. Came out 5.75%

Even neglecting SnD and DST the amount of attacks for my setup still remains 2:1 so the % remains the same. Yay. So totally done with math for the day.

What I generally do is, say you have 101 auto attacks 5 of which where WF and you had a 2.8 speed main hand with a 1.4 speed offhand.
100-5 gives you 96 auto attacks.
Now the ratio of main hand hits per time period to offhand hits is 1:2 so we assume that of those 96 auto attacks 32 were main hand and 64 were offhand. Then work from there.

Just another blanket nerf caused by arenas ?

Have the feeling Blizzard is starting to completely ignore the PvE side of things and is determined to actually make Arms a pure PvP spec again.

Updated my post.

This doesn't touch on the cascading effect of rage loss as RPZip mentioned, and what that means for special usage.

So, what's better now for the rogue group: Instant Poison + Grace of Air, or Windfury Totem?

WF still

Adjusting the Warrior DPS Sheet I get a drop of about 9-10% for DW too.
Still way better than Grace of Air.
