So it sounds like the two constructive ideas most of us are digging is possibility of mounted combat or mounts slowing with damage. Either of these, or both, sound good to me, but I favor the mounted archery. Personally I think people should be able to turn more than 90 degrees and fire back at least somewhat. Mostly because I think it would balance well when they're watching you pursue them they aren't watching to avoid running into trees. But that might create some pve issues with kiting mobs too easily.
