Anselmet, well said, to be honest AST really is in the best place it can be in right now with WHM right there with it, the problem is like you said with SCH. If it is not keeping up then that is not the fault of AST or WHM.

Personally I never liked how a SCH's best heal "Lustrate" (I say best because it has a cure potency of 600) is locked behind an Aetherflow requirement, as a lvl 50 SCH (before I even got AST I believe) I felt dreadfully underwhelming in my ability to keep people alive and with the release of SB that is even more so, I often times dont like playing SCH cause I know alot of it demands Aetherflow stacks. Yes I have not taken SCH into a raid, but I have reasons not to.....it is often times not fun for me...am I saying I cannot handle the class? No, am I saying the class is underwhelming right now? Yes, and as you have stated Anselmet, that is no fault of AST or WHM but Square Enix not having the foresight to properly tune SCH, as you say, the class is really clunky.
