Won't quote entire thing Eremor since it's long but I could definitely get behind a class that fills the sort of role you describe... though I wouldn't give them haste personally, damage and enfeebling is enough. Also haven't they hinted at time mage somewhere? (they'd get slow and haste spells basically)

I like that the enspells described are the elements mnk doesn't use and at the same time they're element damage + enfeebles which opposes mnk's element damage + buffs.

The composure skills/traits seem less focused than the rest of the class and I'd have liked to see some combos that use both spells and WS; as a random from-the-aether pull, silence (silences target)->stifle (extends duration of initial silence and turns single target WS into an aoe with silence effect.)

9/10 otherwise.
