I'd like to see a diversified form of the Freelancer mod that changes the player's responsibilities as one gains rank, up to providing additional quests and the like (even if they're ones very local to the force you're within). In a game essentially about warring factions where one does essentially as they please, there's small reason not to have this kind of gameplay element, barring limitations in development time and whatnot (which is what I suspect is at play). The Freelancer mod was a good start in terms of providing a feature that was glaringly absent from the core game.
