Ohh, tough one for me. But a) Jedi Hero because you have one person who almost undefeatable, you're more likely to win, and it's a easier. B) Elite Training- just this alone make things go smoother, you get through the level quicker, and I don't get killed as quick. C) Bacta Tanks- when I'm some where that doesn't have a repair droid
you can regenerate your health.
