heh, I started off with the guardian/weaponmaster and went to the guardian/marauder. those were always my favorite but I never tried anything else. then I tried the sentinel/watchman and was amazed by the crazy skills. now I'm going to do a sentinel/weaponmaster build.
edit: I have to say that I always use force confusion on everybody in the trayus academy and just stay stealth and watch the fight. I never lifted a finger except for the turrets. one game I cheated otherwise I dont' think I could've done this but I used force confusion on kreia and laughed my ass off as her own lightsabers beat her up.
