I was able to get about 1500 dps on a target dummy self buffed. My affliction dps on the dummy was about 1450-1480 tops. Im guessing as well with the scaling of destruction it should out DPS affliction in raids pretty easily. I was able to try it out last night in BT on illidan and was able to still pull off about 1.1k dps. Being that I was in my SR gear and I couldn't use fire spells in P2 I think it worked fairly well. I'll have to try it out on some other fights in BT tonight.
My rotation was CoE>corruption>immolate>incinerate
had imp out on defensive
