first off, sorry i don't add an armory link, but i don't want to log onto my char to get my retri gear on. here is a warcrafter sandbox one:
http://www.warcrafter.net/sandbox/147009
as it says: i could reach 2.6K DPS before patch 3.2 with titansteel destroyer. i recently got edge of ruin. i switched gems around to make up for the lost hit rating, and the problem is that i had a TRULY MASSIVE DPS loss. i went down to 1.6K DPS. i am not trolling here. really, i could get 2.6K pre patch, but only 1.6-1.7K postpatch (on a targeting dummy both), selfbuffed.
i think it is because i lost 8 hit rating (coming out at 244 rating) and about 2-300 AP, coming from 3.4K without might. note that a lot of the epic gems are not yet into warcrafter, so where you see 8 hit/8 STR, that is 10 hit, 10 STR.
i repeat, i am not trolling here. i am serious. i use might, retri aura and SoV. my FCFS is CS/HoW/DS/JoL/consecration/exo/holy wrath, like prepatch. i tried to move JoL and CS around, to between HoW and DS, but i would get more GCD issues.
