This is not a photoshop, 80 twinks can really pull that much dps when fully geared.
Here is a SS of 500k DPS on the target dummy. I pulled 920k on Putricide and 850k on Sindy, I somehow messed up the screenshots in paint so I'll get new ones this week when I do ICC. Sorry for the inconvenience.
4 piece Tier bonus = 18% increased damage when mirror images are up
600 herbalism = 90% haste 20 sec buff over 20 secs
600 tailoring = crazy intellect buff on proc
MoP 409 pieces = 70% crit ( 105% crit on fire spells) WITHOUT procs
Windsong on staff = 150% crit, 120%+ haste and 100%+ mastery at all times
Currently working on a Warlock tank, lvl 84, 340k HP with 100k+ ember tap heals and 200k+ 1 sec cast chaos bolts. Come at me PVP
