What about more blaster villians? Right now, the blaster are good-4, evil-3. You should add either Durge, Cad Bane, or Thrawn to that list.
And Kyle Katarn would be nice, but hes not in the movies.
For villian Sith, you could add Starkiller, Maris Brood, and/or Emporer's Shadow Guard.
You should add Shaak Tii to the heroes list, in addition to Luminari Ulunduli, and for the fans: Jarjar Binks and Admiral Ackbar (spawning with his phrase: ITS A TRAP!)
