Damn right Storm Hammer, If you can't beat it with saber only, you haven't beat the game. The next time, I will try saber only and no force for the entire game.
Also, a way to test your skill: Go to a heavily enemy populated level and see how many kills you can get in 5 minutes. My first try, I played level 6 I think and got 50 kills. Saber only of course. It helps if you have someone to count your kills.
The Force will be with you...Always.
