OK, SW: SAGE did it, and the horrible 4e is probably doing it, and D20 Modern did it too. How about adding Talent trees to each class? Perhaps even rather than the exta abilities per level and specialist schools? Just a thought, but it would add more versatility to each class and make it easier, in my opinion, to balance everything. Preference wise, something along the lines of way SW:SAGA did would be fine for me.
