WHM DPS is still pretty alright, but come Holy it's pretty high. Holy was pretty much the 2nd best AoE around (and may still be in terms of potency?); it's just that it's a burst and nothing more. The MP drain on it is ridiculous even if you get Shroud of Saints on.

It may be 'out of hand' but remember in about 5 casts you've pretty much depleted half of your MP. Where as a BLM can just umbral ice and right back up.
