I very much doubt we'll see a faction rework for jawas, nor am I calling for one.
I just figure it makes most sense for CG and the game in general for as many toons as possible (or at least each faction, if not every toon within it) to have an actual use for something in game. Yes, the jawas weren't good in arena or any other game mode for that matter, but they were needed to be able to farm one type of mod in the game, and that's fine. One small purpose is better than no purpose at all. But as it stands now, they just took 5 toons from their game and made them 100% irrelevant.
