at gamefaqs I learned that cahracters will have innitial 'classes' and then gradually spread outward. So they have originality and stuff that they are good at. I think you could probably fit the FFXII characters with classes.

However, I think that they will probably 'mix' classes together, makig some original stuff. Obviously FRAN is an archer... that's all I can think of.

Also, it was reported that there would be a LOT of characeters.. like up to possibly 13 or so... tons of characters, some optional most likely (FF6 anyone?).
