Which healer do you find the easiest?

[Semirhage]

Why you no Like White Mage?

The impression I got from your post was "Play AST or SCH". I ask because maybe I am missing a mechanical reason to not like WHM.

WHM has fewer oGCD heals and fewer spaces to weave them than the other two. Also Assize is such a good damage cooldown that holding it for healing is rarely a good idea. So WHM's only consistent oGCD AOE heal is Asylum.

Without as many oGCD heals you need to interrupt your damage dealing more often.
