Sometimes, it seems mounts move just too slowly, especially when you're on the Magitek. Maybe it's because you're at 8,30 in Coerthas and you're trying to get to Naul at 29, 12 (these are made up numbers. I don't remember the grid in my head). It would be nice to have a Sprint ability for mounts as well, or at least have a special green you grow to feed your chocobo so he can dash.
