I think when you progress a lev certain things should automaticly go up depending on your class like in dungeons and dragons and baldurs gate (i use those as reference alot).It would make level progression more exiting.
I think that leveling up just has to do with how much u train. Like on Morrowind i trained for a month just goin around ghostgate fighting. I love training. But in Oblivion they should make the leveling a little more fun though.
