Of course if you're also max lvl, you can only hope to notice him before he attacks you so you can mount up your flying quickly, but still it ruins the immersion of what you're doing. If you're not eligible for the flying mount (As in low lvl) you're basically fucked.
Having to be equally "strong" on the mount side creates equal opportunities, nobody can chase you, try to attack you, they do some dmg, you still run away, they mount up their flying and catch you up in no seconds, with ground mounts you will have a way out, if they chase you and attack you, and you're still on you're mount and they mount up, they won't catch you, so that will often be seen as a decline to fight, unless they're persistent and follow you till the end of the world, which not that many cares to do.
And with exploration on the ground brings less knowledge of the area around you, exploring on flying is easier, but you'll just see everything, I feel if you're doing it on the ground you'll be more surprised to what you'll find around you.
