I'd like a drake.
As Esk said I hope they give us a quest for get the mount, not just that it appears of nothing.
Btw I dont think that implement some mob mounts (not every mob in the game) just for ppl who stay all the way til 2.0 will make FF a wowclone, cause all the other new players will ride a choco, and the dev team can make chocos more important than the mob mounts with breeding.
