Hope they get magic right this time. So disappointing when I can tool around with enchantment/alchemy to enhance blacksmithing and get my weapons to do sick damage even against the ever-scaling enemies, but there was no way to raise magic damage past what was available in the perks.
You had to use enchantment as a mage to make it where your gear allowed you to infinitely cast spells just to have a chance, and even then with the "BLAAARRGH ZERG ZERG ZERG!!!!" style of enemy AI, you could still wind up getting your face raped because you couldn't kill those ****ing Draugr Death Overlords before they ran up to you and sliced you into quivering bloody sushi.
Oh, and bring back the spell creator from Oblivion.
It wasn't all bad though, I did something similar to this with my mage, and basically turned him into the ultimate assassin. Quiet Casting combined with Assassin's Blade, and enchanted gear that allowed for infinite casts was really damn fun.
