You gain more Weapon, and Armor Xp per fight on higher difficulties, because they're based on Damage Dealt, or number of times you get hit. So, on Master you have to deal more damage, the combat lasts longer, you take more hits, and earn more XP. Always train combat skills on the highest diff you can survive (Weapons, Armor and Destruction, the others don't matter as much.) it just goes so much faster.I change it as i level up. The reason for me doing so is because starting off i don't need the challenge as much as i do the experience, as i progressively get stronger, i then need the challenge as opposed to the latter.
On Novice, you spend more time running between fights than actually earning Combat Experience, (and there's no Athletics skill.) so it takes forever to level.
