Theres nothing else to do, lets brainstorm and make it better. Its not hard. Lets balance it. You and I, right now.
I propose mounted combat. All weapons and spells are capable of inflicting damage from mounts. You could base this on the base weapon/spell skills themselves. Have perks, or have it determined by stamina. Your thoughts on improving it?
Significantly faster than people, sprint button gallops for significantly more speed.
Extra speed of the horse increases damage, being stationary would reduce damage (because of the reduced ability to swing your arm, etc). This makes it cumbersome in battle.
"Frightening" a horse could cause it to buck, knocking you off.
Can't block while on horse back, individual swings are slower
Running out of ideas.
