I cant see why they wouldn't just add all of them, i guess they just want to see if any can reach a certain amount of votes. I chose mixed races because personally, I'd like to see a Chibi Cat.

Also, they can possibly make a viera-like race out of Miqo'te + Elezen. Longer ears sticking up like a bunny, tall, sleek. Etc.

Give Galka their tails back too while you are at it :P
