There's so many caveats to get apples-to-apples comparisons, but I want to at least get within an order of magnitude of the power of different specs. I'll also take links to actual vanilla WoW screenshots on Patchwerk and throw them in the spreadsheet as well. Starting baseline:
--6-minute Patchwerk fight
--No Naxx gear, legendaries, or AQ gong items
--Document every buff and consumable it requires to get that DPS (Manual Crowd Pummelers for feral druids, mana runes for balance druids, etc.)
--Most favorable race
--Most favorable raid comp (e.g. Horde gets Windfury in their group)
--We'll ignore threat (for now)
--I'll make a google spreadsheet for damage using 0 debuff slots, 1 debuff slots, and 2 debuff slots
Debuffs on Boss, I need these fact-checked:
Sunder Armor
Thunderfury
Deep Wounds
Thunderclap ?
Gift of Arthas?
Curse of Elements
Curse of Recklessness / Demo Shout (did the AP reduction stack)?
Curse of Shadow

I also don't know off the top of my head what the optimal specs were (like warlock was 30/21 something wasn't it?) so I'll just list all the specs
