SCH needs some nerfs

But you don't address the core problem : lilies. Let's all agree. We're speaking of high end content. So we won't heal with GCD spells.
I would keep divine benison as it is. You can spam it quite frequently, even with no lilies.
Your assize sounds strange to me. We don't need more MP. It's actually one of the best WHM abilities as it is now. Maybe buff its healing/DPS potency.
I like your presence of mind. But you lose what's good in current presence of mind.
So your plenary is a soft excog, with a defense up buff... makes sense in a way. But that does not solve the clipping.

i tried to envision with current lilies system in mind granted system is horrible for high end healing (just make crit regens or something count on regens to get them) i also didn't want whm completely stepping on ast toolkit with balance etc so i tried keeping the pure healer mentality to get a single target increase = to rng balance draw need to use 3 heals ast is still better with it being ogcd and no mp but whm more reliable etc.
with the assize 10% mp it was meant to be gives free 10% of caster's maximum mp to all players hit and i have no idea how to reduce whm clipping issues short of changing a few cast times. As for presence of mind i couldn't see them having both a spellspeed increase and mind increase and choose the one i think be more worthwhile for whm
