Well, it's not a huge difference, but again, it matters some. Lets take a look at MH Mongoose as an example.

Lets assume we're using Talon of Azshara, and are gaining enough energy for a Sinister Strike every 3 seconds (in practice, it takes a bit longer than that, but, as a ballpark figure, it'll work). Based on the way the normalization works, regardless of haste level, the autoattacks will generate 1 proc per minute. Now, if instant attacks are *not* affected by Haste, we will have 20 SS per minute, each of which has a 2.7/60 = 4.5% chance to proc, so we gain an extra .9 procs per minute from instant attacks, for a total of 1.9 PPM.

If, on the other hand, we have, say, 35% haste (which is trivial to get to, particularly with 2/5 T6), our Talon is now effectively speed 2.0, so the proc chance goes down to 2.0/6.0 = 3.33% chance; hence the 20 sinister strikes per minute only generate an additional .667 procs, for a total of 1.667 main hand mongoose procs.

So, it's a difference of about 14% in the number of MH procs, which equates to an uptime difference of about 11%. Hence, there's an 11% difference (or so) in the damage contribution of Mongoose - that strikes me as relatively significant.

Not that I disagree with you at all, since splitting hairs is by and large what we do as theorycrafters. My point is mostly that, as long as we don't know whether special attacks get penalized or not, we're still not going to be too far off regardless of which way we model it.

As a quick update: I hacked up some estimates of assuming

a) Haste Nerf
b) Dragonspine Nerf
c) New findings on Haste/PPM.

Findings are pretty interesting; for one, agility does indeed pass hit in terms of total utility per point (at least, by weighted total if not by actual damage output - hit still has the damage edge).

Additionally, the ranking of the endgame trinkets is as follows:

1) Dragonspine - 209
2) Ashtongue - 173
3) WSC - 172
4) Madness - 167
5) Tsunami - 157

So Dragonspine is still the best. It's just not quite as mandatory as it once was.

alright I finally got my character copied over. This is about 55 mins worth of combatlog. Used bt trash mace 1.5 speed and arena sword offhand 1.5speed. No instants or finishers. I used blind I think 3 times, twice near the end because I ran out of potions. Mongoose on both weapons

this is of course to test out internal cooldown and PPM of tsunami talisman on the PTR

Will you have this updated on the latest spredsheet?

Yes. I'm not going to bother releasing a new version until the patch gets off test though; while they're still changing things I don't feel like trying to keep stuff updated.

Analyis of Tsunami Talisman data:

Shortest time between procs: 45.187 seconds, occurring twice.
Number of crits that occur at least 45 seconds after last proc: 443.
Total procs: 45
Proc rate thus lies between 7.3 and 13.0 percent.

Now, what I have in the spreadsheet is 10% proc rate, 40 second internal cooldown. From this data, it looks like more than a 45 sec internal cooldown. So either this data set is flukishly devoid of procs between 40 and 45 seconds (as in, there were 92 crits between 40 and 45 seconds after last proc, and no procs), or it's been nerfed slightly, or I have the cooldown a bit wrong on live. I'd say the third is most likely, but if people want to do additional testing I'll certainly crunch the data.

I know you're not thrilled with the modelling of +skill in the spreadsheet, but how certain are you about the DPS value of [Gloves of the Searing Grip]? Given that we're on the cusp of an Al'ar kill, and we haven't yet killed Leo with huge demand for T5 gloves, and the uselessness of the T5 2pc bonus, I'm wondering whether it would be worth it for a rogue who has weapon expertise anyway (we have no mutilate rogues as active raiders).

from what I know weapon skill works just fine in the spreadsheet as long as you have at least 355 weapon skill. So unless you dont have weapon expertise, it should be giving you a pretty close assessment of those glove's value.

Mojo: There was some discussion on the weapon skill adjustment thing about the actual value of weapon skill, whether or not it scaled linearly, etc. Should I just take it at face value and say "It will be at least the DPS noted in the sheet" and deal with it?

Think we can have a feature on the next version that can show AP/crit as well, aside from just hit rating?
