Healer DPS is absurdly strong.

BiS BLM = 600+ int
BiS WHM = 600+ mnd

Cleric stance swaps the mnd/int value, and adds +10% damage.

Holy = 200 +10%
Flare = 260

WHM can cast Holy 20 times before they run dry on MP, BLM can cast it 4 times before rotating again.
In any short group pull with more than 3 enemies, WHM DPS can arguably be the strongest DPS in the game.

(This only applies to trash pulls! Hehe)
