I would give HK-47 more feats. He's hugely lacking in them now, for a combat droid.
T3 pawns his ass .
EDIT: Reading your entire list I hardly call that balancing. Or even anything remotely like how I would modify the game. Sounds to me like you extreme buff enemy damage as only con to difficulty, and compensate by making all Jedi gods. That's not my definition of 'balancing'. Actually, because of the AC one can get in the game with your changes, I see enemies having a hard time getting that increased damage applied, overall making it a lot easier. But I suppose others may like it.
What do you suggest as thread name instead?
