I remember on battlefront 2 instant action there was a mode called assault. Which you could play as a jedi or a sith. The thing I'm asking is will this be in it or will it be there in the next star wars game.
That would be fun, but that hasn't ever been brought up by DICE/EA and I seriously doubt that it'll come back. A lot of it is because this game only focuses on the original trilogy. The only way of course that could change would be through DLC later on.
