I've been wanting character recustomization for a long while now. Most other MMO's out there have it in some form or another. I'd pay credits, cartel coins or if it came down to it, real money to take advantage of a recustomization.
I had just signed into the forums for this exact same reason. A shared legacy stash (similar to the stash you can get in diablo 3 and other dungeon crawlers) would be an awesome addition to the game.
