I'd like to see different class options, that way not everyone is the same, lets take fighter for instance, warrior could be sword based with defensive abilities, barb could be axe based with offensive abilities, and dragoon could be dragoon like (superjump and jump) with both offensive and defensive (bandage or pray, along with sonicboom)
ie, get fighter to level 30, and have the option to change to one of the 3 higher tier classes, creates some diversity and keeps things from being boring

dont need everyone who goes fighter being the exact same
