there is a way to turn off certain force powers in a server. For example, i started a game once on the zone (ya i know it sucks but i wanted to play some newbs) and i started a game and had the force level on Master. Then i loaded the game and brought down the console. and typed this one thing, which i forgot what it as, i would have to be at home to check. I am at school now so if i have time tonight i might post it. But anyways, i turned off light and dark powers and kept push and pull and stuff. I just like push.
I kept all the neutral powers, however you can have a variation. Like just having jump and the saber levels.
