@Lycinder: Ahh, I missed that one. Well, I don't know if I am playing the same job as the guy who wrote that, then. When you micro everything and maximize your throughput, SCH definitely feels busiest of all of the healers. If anything, I think transitioning from SCH to AST is easier than WHM to AST, because of the fact you have to (or should) micromanage your fairy and also keep track of an interval-based resource without losing efficiency (Aetherflow stack usage). I'll withhold final judgment until I've actually experienced some level cap content on an AST, though.

I will, however, agree that SCH has the most lenient skill floor but that is hardly relevant here.
