Kind of a minor thing, but now that I have more than three it sorta irritates me having to remember which number corresponds to which class, particularly when I have multiples of the same one (dangit, is number one the rate of fire Assault, or the armor Assault?). I think it would be cool if the next update allowed for labeling the custom class to make that a bit easier.
This is a great idea. The info wouldn't need to be sent over Xbox Live, so the game would still run just as smoothly, while only adding a kb or two to our HDD.
