lol I think we've had several threads about this topic.

I agree, I wish there were more diverse options...but it is what it is. And its been said that The Hrothgar and Viera will Possibly be the Last Races to be added, because of the large undertaking to create them in the 1st place, and with how the game is designed, they would need to fit TONS of gear; Past, Present and Future.
Id love to See Bangaa, Lupin, and Ivalice Moogles added to the game, but I think the chances are next to none.
