Yeah. Putting mounted combat aside for a second. The most important thing that they need to do in regards to horses and mounts is fix the :swear: mount/dismount animation and make it much, much smoother. Something akin to Assasins Creed. Maybe not quite as fluid as that, since our character would be weighted down with armor and gear, but at least something that lets us move quickly from horse to ground and back again.
Yeah. I think that just jumping on your horse should trigger an animation that gets you in the saddle. Red dead redemption had it. If you jump off something onto your horse in that game you just get right on.
