This is an inherent problem with the star wars universe. It is hard to really make other options truly compelling next to the notion of a playable Jedi if the game is going to be combat-centric.

Everyone else playing other options are doing their best to simply not conform to the allure. This is why I wished the game adopted a 3 person playable party similar to the singleplayer games, as this would allow me to have my Jedi guy, but also my Smuggler guy etc. on the same team.
