Give healers a dps rotation and when they successfully complete it, there is a small aoe heal similar to but not as powerful as assize. We could also give the other healers an ability to mark a party member that would get heals when we do single target rotations. Or if you want to be fancy give us 2 different effects we could throw on a party member, one that gave them a heal when we complete a dps rotation and one that gave them a shield.

Or give us a couple different rotations or a branching rotation one that ends with a shield and one that ends with a heal

Instead of just dumping more and more worthless healing skills on us, give us dps skills that almost act like dots and a couple single and aoe heals for emergencies.
