I just became privy to this thread so I don't know if anyone has made this suggestion or not, but back in the day when I played FFXI I always thought to myself that there could be more mounts besides just Chocobos. Specifically there could have been racial mounts. (Like Galka riding Dhalmel and Tarutaru riding Crawlers) So, in the same spirit, I think it would be cool if there were either some kind of Race specific or nation specific types of mounts that could be used for transport or other specific purposes. XI had a lot more mobs to choose from that were mount-worthy. I can't think of all of the possibilities for XIV but the idea of a Roagadyn riding an Aldgoat or a Lalafell riding a Dodo appeal to me!
