DLC = Not cool. Head gear for mages = not cool.
What would be cool is a patch for the glitches and bugs that fill the game. Nothing serious (well, except during the 'Paragon of her kind' Dwarf main-quest), but irritating graphics glitches and bugs all around. Fixing those would be cool.
The DLC can come when the core game functions as intended.
EDIT: Also, remove the unintended eye-candy. Wait...its very much intended. Let's just call it blatant and nerd-fishing.
I for one refuse to believe that an armor that a leather armor that barely covers a woman's torso offers higher armor rating than the fully covering chainmail, no matter how higher tier material the leather was made of. The game otherwise manages quite well to portray a medieval fantasy setting, but then discrepancies like this pop up. Silly headgear and bulky-looking plate-mail armor is almost an integral part of the territory, even skimpy wilder elves I might somewhat understand as part of severe in-game cultural differences, but showing rendered skin for its own sake is just plain marketing tactics for 15-year old boys.
