I can think of more. Randomly rewarded items based on the things encountered (or stumbled across). Stats available to be customized by each user for themselves, like 100 posts gets you one point in a class tree.
Assign spec altering stats to some of the items you can get, OOOOOOR have a whole new set of items come out with the stats and have a "battle" avatar you can use to show up in the game, this way you have armor that actually adds protection and whatnot.
