The real major drain on Ast MP is Malefic. It’s the weakest single target dps spell amongst the healers yet is just as expensive. If they reduced the MP cost from 400 to 350 that would actually solve a lot of Ast MP problems. A majority of Ast abilities are on 60s cooldowns and don’t require any resources to use so they should make up the bulk of our healing. Shields aren’t meant to be spammed so lowering the cost doesn’t really solve anything.
