But any improvement over Oblivion will be just as welcome as Oblivion's combat was when compared to Morrowind's.
So you want to see a more Assassins Creed approach to it. I could agree with that, but then combat would just be too easy. I think it should have a more fallout 3 approach where you weaken your enemy, then when their health is low you perform a fatal deathblow. Kinda like in mortal kombat, you can do certain finishers that apply to the class you chose, or what angle you are facing them, or if you are in stealth mode or not
