They'll have to rework something though. For once AST and WHM are in direct competition with each other for the one pure heal spot and Diurnal AST is currently miles ahead of WHM. Mobile, no weave tax, utility, raid buffs and a better toolkit in many ways. It'll be interesting to see how they handle things like Neutral Sect or if CU will keep its 5 seconds of mitigation on use. Knowing SE, they'll rip AST's toolkit apart, then buff it like crazy all expansion ...again.
