Just from other ff games it'd be cool if you could do more with the chocobos. Everyone wants special clothes or something you could do that with chocobos since in 7 it was a gigantic process to get a gold chocobo and would show how much was put into it, not just that you started in the beta. Plus then maybe they could run faster which would be cool and if you could develope them more maybe there could be chocobo dungeons where it's four players and 4 chocobos
