Putting my rhetoric on melee RDM and how it needs to take FFXIV by storm aside for the moment, I wanted to comment on the possibilities of a mount system.

Mounts in the final fantasy series have been limited to chocobo for the most part. We've always had a wide variety of colors and such, but in the context of an MMO this is quite limited. Just like there are people who collect gear, there are people who collect mounts and find that activity fun. As such, I think the developers should look into expanding available mounts beyond just chocobo and going into some of the other sturdy and capable beasts of burden of Eorzea. Goats and rams are a nice alternative (I'd get some amusement out of seeing my lalafell riding on the back of a billygoat from point a to point b, for instance). I'm sure we could bring in bugards, dodos and ewes as well. The idea is to let players choose their ride and go with it.

At the same time, I would like to ask the devs to be very careful if they are considering implementing any type of raising or breeding system for mounts. For one, it's proven to be quite inconvenient and not well thought-out in FFXI. That's one of those mistakes that should not repeat itself here. I'd lean more for a type of system where you get your mount and use that to move about the world.
