Casters can't DPS him with dispose going, melee can't when math is up

All casters, with the exception of RDM, have instant cast GCDs always available (and even RDM can get GCDs if their manas are good, they have swiftcast etc.). It's not going by the rotation but it's better than 0 dps. Math isn't a big loss for a melee, because you know, you don't need to stand in the circle the entire castbar.
