I agree it would look better, but since with version 2.0 we will be getting zones that take a little time to load between each one, I think this issue will be addressed then. Or at least, I'd raise this point again if when approaching a town once we have the new map and zone system, we still are met with the 'chocobo force field'

But no, it shouldn't be too hard to at least throw up a prompt that says 'Dismount' Y/N even now
