Please no level scaling.
Oblivion was the worst experiance I ever had. After killing tons of demons I had problems to kill goblins and rats.
For almost every RPG I have played there were endless discussions of "easy mode is too hard" and "hard mode is too easy", both at the same time.
I think one problems is that Larian thinks "Players feel smart when they think they find out how to break the rules".
As a result we have trowing potions, fighters using scrolls and equipping lots of items that give extra damage to action x,y,z and so on.
My opinion: No, those things do not make the player feel smart, those are just idiotic rules.
