To Yoshida-san and FF XIV Team:

I also vote for Chocobos Only to start with.

And a Chocobo Breeding System like Final Fantasy VII, to customize, get rarer, faster, stronger Chocobo Mounts that way. They can dovetail that system with a whole new Gold Saucer Chocobo Racing Sub-Game, which could be a good form of entertainment, a Gil Sink, and a way to earn rare items all in one place.
