When you have mounted your horse you should be the one that is attacking the target and takes the damage or gets attacked by a creature and not your horse.
The horse should also stay with you when you dismount when outside of a city and when you enter a city or town you should be able to leave the horse there and it should always stay there and not run away.
I really am looking forward to the dawnguard expansion but really hope that players will get the chance to re-visit morrowind and cyrodiil and maybe even the black marsh area as future full expansions to the game.
Other than that keep up the good work and one more question, players were able to get a castle in Oblivion and its would be nice to also be able to do so in Skyrim.
