For me it seemed really silly to wholey copy all the races from FFXI but totally lose the character of the races they copied and make them all so generic, at least it means they can make animations easily portable to ALL races I guess. Sure they used motion capture but they have no character. Mi'quote are just a pretty human race with fluffy cat ears and a stuck on tail. To me it seems they used more expensive technology to animate the races and so just made them universal to all races to be cheap.

I'd take the work of a talented model animator over motion capture if like with FFXI they do a better job.
