ok, so you guys have convinced me, that for the sake of the healers and the mage (including myself), that i shouldnt be a greedy bitch and play demo to provide the buff... BUT i have one last question
for my personal situation, out Shammy goes Ele for 3 fights: Yorsajh Warmaster and Ultraxion.
I could care less about Yorsajh and Ultraxion since we have them on farm, and I would remain demo for those fights regardless.
that would leave me with the viable option of playing Affliction on Warmaster without sacrificing the 10% buff for the raid. Is it worth reforging to full haste for the sake of 1 fight? probably not. So even if the buff is present... would it just be worth sticking with a 1993 haste reforge then full mastery, and staying demo on all fights? or would switching to affliction with those stats not even be worth the switch? (sry if that got confusing, but this has been my biggest dilemma in deciding what to do, and I'm sure others might be in similar situations)
