The mod DICE city for bf 1942 had a bulletproof (and knife proof) shield in some of the kits that would be raised if you held the attack button. An invisible version of something like that could be used. The lightsaber should be a onehit weapon, but the lightsaber itself being equiped could have a large shield area of hitbox in front of the player that mitigates damage by 90% this would make duels take longer if both players are actively engaged, but if one gets behind the other, one slice cuts them down, so they are not just standing still and slashing. This also means if you want to shoot the Jedi, shoot them in the back. right click could be like an alternate attack that brings up a 100% shield but immobilizes the player while it is up, allowing the enemy to circle him and kill him if block is abused. This would probably create the most fun dueling system the bf engine can offer. The jedi kit could also have multiple lightsabers available in the inventory (or as unlocks) to represent different styles of attack. Jedi acadamy has light, standard, heavy, dual wield, and double blade. with different advantages and disadvantages for each. One of these could be a throwing lightsaber.
