Allow us to test different races without using Fantasia

[Zanarkand-Ronso]

So a new player has to make 12 characters to see which voice they like and which combat voice they like, what a nice design.

Or they could be shown on the main creation screen like any decent game would do.

I did it just fine. So I know its possible for anybody to do. Its how I chose my Avatar Im playing now.
Anything more then that and, I mean you are effectively asking to be able to just turn into another race; changing fundamental data from your Current Avatar for free so you can test it out. What you want to do is a paid service.
But if you just wanna see the other races and options, you can just make a new character and look at stuff.
