The number I posted in the first post is strictly from fighting the last boss of Gun'Drak. I cleared the recount totals prior to the fight. As such, this number was achieved with bloodlust up almost the entire fight (since I killed the boss before bloodlust ended). Also Elemental Mastery was up most if not all of the fight as well

On trash I do not get these numbers, though I suppose I could if I had bloodlust and elemental mastery up and pulled 5-6 mobs. Usually just running through trash in Gundrak using my /castrandom macro I get something like 2100 DPS, no cooldowns used, and I have to heal quite a lot more when 3-5 things are beating on my tank
