Burst damage ?

WHM have it ! I do 1000~1100 Damage with Holy

Holy's like the WHM's Flare, it's AoE, it hurts and to top it off it stuns.
Oh yeah it costs an arm manawise but to hell with it!

WHM have potent DPS and healers don't nead any more of it.
SCH have dots and the longer a fight lasts the more they'll dps so they don't really need more than that imho.

For me it's like so :

WHM > AoE Burst high Damage high mana consumption.
SCH > AoE DoTs with low Damage, low mana consumption but higher Max Damage the longer the DoTs run.

This is ofc my personal opinion.
