Eh, even outside of not being able to just dismount wherever I want (and it's not just wanting to fall to my death - there are a lot of statues, pillars, hills, rocks, etc that SE hasn't bothered allowing you to "stand" on, which means you can't "land" on them, which means you can't dismount to stand on top of them), the whole having to get all the way to the ground before dismounting (and not being able to dismount by using an action) is really clunky. The transition between being in the air and being on the ground is not smooth at all.
