This really doesn't have anything to do with mods, but it has always annoyed me and I think it would be great if you could fix it. The game has too many characters that are underpowered and unusable. I used to play another ftp game on pc, Marvel Heroes. With that the developers alternated between bringing in a new character and revamping an old one.
I think this game would benefit greatly from adopting a similar pattern. Too many of the iconic star wars characters are underpowered (Boba Fett for example). I know new characters drive profits, maybe having a sale or something when the revamp goes live could help with that.
I think it would also help in that players would feel that the time and money they invested in this game is being respected.
