I played my Jedi Shadow up to 50 even though I main IMPs for a number of reasons, one was to PvP with less huttball and be on the underdog side, and the other was the feeling you get when your actually saveing people and planets. This IMO is more heroich then the bounty hunters "Get a lead on a guy with a bounty and follow it" or the SI selfish quest for more power. IMO it is actually better overall story when you are saveing masses.
