I understand, live and love the destro spec, rotation and my dps numbers. From reading these fourms and raiding in 25 mans only to understand that EVERY good mage is arcane so that leaves out the scorch buff on target. For example if there is at least 2-3 locks in the raid group pushing 5k dps, is it benifical for all the casters in the raid group for one of the locks to take the points out of ISL and put it into ISB, being that hunters with hunting party and Ret pallys with Judgements of Wise give the same mana regen buff and from what I see it's always up. My question is this, if one of the locks did apply the ISB buff on target from aftermath proc and pyroclasim or some where inbetween rotations, is it worth crippling his/hers over all dps just to boost the rest of the raid.
