In Star Wars Batllefront, the only weapons avalible are the blasters and some misc., but that ain't importaint what so ever. Only the Jedi have lightsabers (duh) and they can't even beat my all time blaster shooting (my highest score was 103 kills single-handedly on the Endor:Bunker map) and even they have to run up to the enemy's to kill them (or they could deflect your shots). Either way, YOU CAN STILL KILL THEM!!! Goes to show you, if you can't be them, you can still kill them. Let's not jump to flashbacks; that'd take more then 1,000,000 words to explain it. To conclude, you don't have to be invicible to top off a lightsaber, just kill the jedi in Star Wars Battlefront.

Big update: On the Naboo:Plains map, I tried to kill Count Dooku by running him over with an IFT-X. I did that for about 2 minutes, and he just respawned. If that ever happens, no-sweat, just try it again when they respawn. Running people over with an IFT-X or T is the easiest way to do it, there are many others. Those; you'll have to figure out.
