howso? from where im standing it sounds like it would only remove gameplay. the whole idea is to travel with your pokemon, to have them protect you from the wild pokemon, to not get attacked yourself. to be able to soar over the top of them would make travelling trivial.
consider spawns; one of the most exciting things there is, to chase it down, make sure you're taking the right route, to get to where it is as quick as possible and beat everyone else, but not to rush and faint yourself back to the back of the pack. to remove such concerns would, in my view, be nothing but detrimental.
