I'm away from my PC for the summer so I can't test this out myself, but now that the player fights on horseback, is it possible for NPCs and Followers to be the same? If so it seems like a cool oppurtunity to add in horse archer type enemies in the planes around Whiterun and renegade knights near the high rock border, and something I would definitely do myself once I made it back to my PC.
Also mounted charges FTW.
