To be honest, I didn't much care for the "light/dark side scale" in terms of reputation of sorts, especially when applied to non force adepts/jedi/sith- basically droids and the vast majority of non jedi. Things such as using the force to corrupt the minds or enemies, settle disputes or determine treachery or basically any manipulation of the force to solve whichever event should determine whether one walks the dark path or light path as it were. Not thievery, unless it could be determined that such and such a character used the force to aid in this.
Different dialogue trees would add more replay-ability from my perspective, I wouldn't necessarily characterize it as fixing anything as some stories are just linear. No big deal if they are done well.
Combat needed some balancing. Passive deflection of blaster shots should be tossed out the proverbial window. I should not be able to leave my jedi character alone and completely unmanaged while half a dozen combat droids fire at him/her, leave and return a few minutes later with the droids in a smoking pile of rubble. Projectile/range whatever weapons need balancing as well. If you were hit with a stun weapon with a setting that could take down a wookie, your character should be unconscious or somehow adversly affected while he uses these jedi abilities to reorient him/herself. Apply rules or status changes in some proportional way for different species or characters with specific feats conditioning what have youl.
