First off, LOVING this game so far. The amount of customization is more than I ever thought there would be in a game like this.
That being said - one thing that drives me absolutely NUTS in any game customization menu, is NOT being able to rotate my character. Hopefully this would be an easy addition as it makes it much easier while customizing to decide if that's the look you want or not.
Again, LOVE the game, few minor matchmaking bugs so far, but they've all worked themselves out for me.
