I'm currently in a pretty good Dawn game and you really want to stick to the 28 point buy. Our GM gave the 2 Jedi Pistol group and even that was a bit unbalancing, but for a different reason. Mainly the Jedi refused to tank with sabers and even use force powers. This placed all fire on our noble while I ran attacks in the hallway(s). We only survived by the grace of a scout (me) who knows how to use smoke grenades and R9 canisters (something made after the module...so kinda cheaty). By the time of the first real "dungeon" I just relented and picked up a survelliance scanner so the Jedi don't need to worry about sabers and powers out.
