This isn't a help desk, and we don't allow personal gear and game play requests in the spec discussion threads. This sort of this is (barely) allowed in the "simple questions" thread. I'll move your post there for you, but in the future please make sure you ask things in the right place.
Well, the reason of my request is because of my dps. I have a good burst and a good initial dps (2 min fight). After that, when FE expires, my drama begins. My dps fall considerably along the fight. The longer the fight takes, more my dps falls.
Until 2 minutes, I can do 33-34k dps. With 5 minutes, even I can use FE again, my dps is 29-30k already (using on cd Blood Fury and Elemental Mastery). With 7 or more minutes, my dps is 24-25k. Fights like Deathwing, I can do only 33k dps.
I know something is wrong, but I dont know what. My rotation I think is correct: Fire totem down > FS up > LvB on cd > ES with 7-9 stacks > LB. I use on cd too BF and EM, as I said.
