I'm sort of wondering if this will end up being true. We have to take into account they only have one Mana Regen move, as opposed to WHM now having two. On top of this, WHM is getting a new reduced Mana proc on Medica, and also has its Freecure, whereas AST only has the instant cast without any changes to MP cost.
While I agree the Mana costs do seem quite friendly, I wouldn't be surprised if MP management became a thing for ASTs too.
