One thing I'd suggest adding to the OP, under the section where you're dividing up the classes, is what exactly entails a 'multi-hit' class, and how it benefits certain areas.
I'm pretty sure it's refering to moves like Double shot or to refer to more useful moves, the BaM's triple / quad etc blows, where instead of one large hit it's 3-4 smaller ones. However I'm not too sure why this allows one to train earlier at certain places as while you do get attacks through mroe often, your'e still missing about the same % as a big hit class would? Does it have something to to with knocking back / interrupting the monsters?
(Pardon my noobishness)
