Viera was in final fantasy tactics its been a long time race in the final fantasy franchise. You say you don't want stuff borrowed from other games, yet the main races for this game are direct rip offs of FFXI different names and additional gender options but thats it. Not to mention FF13 2 lightning returns or whatever events coming, not to mention dragon quest events coming so meh.
Personally I would love a viera dragoon or a vierra thief/assassin/ninja if they ever released those classes. Just my 2 cents
