This might be controversial, but the bulk of important healer gameplay happens on oGCDs. Not on ye olde Cure 2 spam piety builds. It would be nice to see a job that took that into account from the ground up, and left the long cast MP spells as a back up for when you mess up your resource management.

You can have a Chemist that uses MP Spell "Potions" as reskinned Cures, but then there's no point complaining when it turns out to be WHM number 3.
