I'd would have preferred a system where you got experience for completing quests.
Doing all these tasks just to get some gold is rather lame most of the time. The only real rewarding quests are the ones that give you unique items.
This.
-Completing Quests and Combat should give you Combat XP which advances Character Level.
-Crafting should be completely separate and you should also have a Crafting Level.
-Skills should always move up the more you use them like the previous TES games, but not advance character level
-Bring back the concept of Primary, Major and Minor Skills and structure the perk system accordingly.
-Primary Skills become - Combat Perks
-Major Skills become - Character Perks
-Minor Skills become - Crafting Perks
