Change AST to HoT healer if we're getting DNC...

[Aeidis]

Thoughts on changing play style of AST to feel like a HoT healer if we're getting DNC and assuming it will be a melee dps style healer? Then we have a burst healer - WHM, shields/pet healer - SCH, HoT healer - AST, and dps healer - DNC.

EDIT: Also makes sense for AST to play this way since it's the closest thing we'll get to Time Mage.
