I am in the process of attempting to deduce a way of finding more realistic raid-wide DPS gains from Expose Weakness. The best way that I can come up with is to find the DPS-gain from 1AP for each of the classes/specs/styles, then I can use those along with a given raid-makeup to get a rough (but much less rough compared to the other options) idea of raid-wide DPS value for a given Expose Weakness.

Now, I realize this is fraught with problems, so I'll list off the most obvious and the assumptions I am looking to be held to solve them:

P1. All physical damage classes value AP differently.
A1. I hope to find an average/rough AP valuation for each class.
P2. Even within a class, different specs/styles value AP differently.
A2. I actually hope to find an average/rough AP valuate for each spec/style of each class.
P3. Within a class and spec/style different gearing levels create different values for AP.
A3. Not much that can be done about this besides getting the actual people in a given raid to calculate out their value for AP. I'm trying to get my raid to do this, but not everyone is a theorycrafter . As such, I'd like to get an average value for each class/spec for at a given gear level, say up to Kael loot, in order to get a more useful number than just using the 14AP:1DPS number (with the full realization that it still isn't accurate).
P4. You're a nub, fill out the spreadsheets yourself.
A4. Well, maybe I am, or maybe I trust each of you to better know your class/spec/play style to fill out your spreadsheets accurately and understand them. And maybe I realize that many of you would only have to do about 2 minutes of work to be able to kick out a value for AP and report it here with a brief explanation of your class/spec/gearing.

Those are the biggest issues I can think of. All that being said, allow me to lay-out what I'd like to get from each of you.

If you could, please open up your favorite DPS spreadsheet and make sure it is up to date (or better yet, update it so that the gearing is around Kael-level). Make a note of the theorycrafted DPS. Next, bump up your stats by 1AP and make a note of this new DPS. Report back here the difference in DPS along with a brief explanation of your spec/style and the gearing level you computed it with (just a general gearing level will do, like SSC-level, or Kael-level, or whatever).

Please note that I also need numbers for tanks! Your dps will increase from EW also ya know
I basically need numbers for every-single physical dps-source, be it tank, rogue, enh. shaman, feral drood, ret. pally, etc. If you hit the mob with something that is effected by AP I could use your numbers!

I'll munge all the data and average them out for similar gearing levels and create a table in this post of the results. From there raids can use the information to deduce a more realistic value of a given Expose Weakness. I say raids can deduce this and not Survival Hunters because finding a value for EW really is useful to a raid as a whole, it will help raid leaders to be able to decide if giving the SV hunter a GoA totem would be worth it or not for example.

Again, I realize I am asking quite a bit, but unfortunately to get a true valuation of Expose Weakness this is the level of work that is needed, and I can't do it alone (I don't have the time or knowledge of other classes/specs). If you have thoughts or concerns feel free to share them of course, but if you think I'm crazy go ahead and keep that to yourself

Using Tunah's spreadsheet for feral druids and my gearset, I got a .18 DPS upgrade from 1 additional AP.

100 AP added 30.47 dps for me on the Rogue DPS spreadsheet.
100 AP added 29.32 dps for me on the Rogue Gear spreadsheet.

As for gear, I have every last piece I could really want from Kara, Gruul, Mag and VR with the odd SSC piece. I'm using dual S2 gladiator weaps.

In general, you'll probably find rogues and warriors benefit the most from AP, followed by hunters, then druids getting the least benefit.

Just a quick check put warriors as 0,38 DPS per AP.

Fury warriors tend to scale very well with AP since bloodthirst which is our main instant is purely based on it as opposed to rogues and MS warriors.

It was calculated last month that Enhance shaman with the Weapon Mastery talent effectively makes 12.73 AP = 1 DPS.

First, that looks to be extremely low for a full DPS:AP ratio. That comes out to what, .079DPS:1AP? Was that number calculated taking crits into account? For that matter, how can a blanket ratio be found for any class? AP value is dependent on DPS, which is dependent on weapon, hit, haste, crit, and ap itself. Not to seem unthankful, but those numbers just don't seem, well, right. Maybe I'm missing something in the valuation you listed, can you link to the post where that was calculated?

I believe he means that instead of 14 ap = 1 pre armor white dps, for shamans it is the number listed. Though I do not believe this helps your cause much at all. I will figure out my own AP -- dps numbers after work as well as that of my pet.

I've been thinking about this Grogg and I believe you could write a mod that would give you pretty decent numbers for EW DPS contribution, although the amount of data it would have to collect/process is pretty significant.

Track buffs on players and debuffs on mobs for any given occurrence of an attack with AP factored in.

Keep a rolling record of the data for each player and attempt to compare each new event with existing events. If two events coincide in every meaningful way, except EW is preset in one and not the other you now have a delta you can apply to previous/upcoming events from that player. Once that occurs you can discard most of the buff/debuff data.

Problems:

-Percentage based buffs/debuffs will skew the delta you are trying to find.

-Main-hand / Off-hand for dual wielders. It is hard (impossible?) to distinguish between main-hand and off-hand events in the combat log.

-Changes in armor altering buffs/debuffs will make the application of one delta across all events of a type difficult without storing excessive amounts of information.

Information you would need:

-List of buffs/debuffs that affect physical DPS output.

-List of attacks that have an AP contribution.

Despite that stuff I think you could generate a pretty good approximation.

I almost feel like it would be less work to simply create a conglomerate spreadsheet from each of the existing class spreadsheets (one that just takes the end values instead of gear choices etc. as input).

Either way I suspect that I wouldn't have time to complete such a task any time soon (cursed rl schedule).

Another option would be to create a log parser instead of an add-on, except the difficult part there is knowing when a relevant debuff falls off the target (there aren't any combat log entries for those, right?).

I feel the best method is just just using a general rule of thumb, say there are 3 Rogues using the 1 AP gives 0.32 dps number, so if they gained 300 AP via EW that means 288 dps added for the 3 Rogues for however long EW lasts.


For a Felguard (who only has 1 special attack every 6 seconds), 1 AP is .17 dps, this is for a raid buffed FG.

Rogue, raid buffed, 100 AP = 33.01 DPS -> 1 AP = 0.33 DPS
