is AST a better substitute for WHM or SCH?

[Pentt]

I think maybe a lot of SCHs are used to maximizing DPS... but one that focuses on heals really can be very effective and is something to see. On the other hand, stacks and CD timers do limit them, but there's little that a succor beforehand and indomitability afterwards won't handle... and there's whispering dawn if even more raid healing is needed.

Trust me, if you're a SCH in savage with an AST you need to be good at healing. You pretty much have the entire raid in your hands since AST throughput is limited and their emergency heals are weak.
