I think I remember reading that some of the different types of mounts included carriages pulled by chocobos that would take you from a to b (like a path travel, sort of like flying from a to b in other games) and of course your normal ferry/boat, airship and rental chocobos. I also remember reading (prior to release of the game) about personal chocobos that you could 'customize' (besides color etc) to be extra storage or find you treasures, be a racing chocobo and dare I say I may have read being able to fight (potentially very limitedly) from a chocobo. Anyway, I think these would be great.

- carriages pulled by chocobos/horses (automatic paths) (maybe possibility of a group being able to travel together in the same carriage)
- rental chocobos
- personal chocobos (customize to do extra things like hold items/find treasures/be speedy etc)
- airships (automatic paths)

I think it would also be nice to have equipment or consumables/items with speed buffs for a gil sink for use in the city and other zones/places where you cannot ride your mount/find a rental mount/carriage etc
(also I think it would be nice if you were NOT allowed to ride your mounts in the city, makes a lot of lag and is really visually unpleasant to see characters stuck inside of someones mount etc)

Anyway, feedback! xD
