From what I've heard/read (I started late shb, if it wasn't obvious at this point) I had the impression MP regen was much sparser in battles, physical DPS used TP for most skills, and part of AST's card mechanics included recovering those resources. It made sense that the variety of support pre-shb AST had was their original take on CHM.
