Good list! Especially agree with #12: Replays. This game deserves a movie maker like Call of Duty has. I have seen so many great duels that would make for awesome Youtube vids! I wish I could go back and record them. I can think of no greater tool to market this wonderful game!
Other than that, I just really want to see more cosmetic customizations and leveling-up perks. This game is just crying out for more RPG-like elements.
