[quote]Force-Trained characters are also the only ones that can reliably wield lightsabers. In any other hands, they would clumsily swing it around until they accidentally sever off one of their body parts with it.[/quote]

Correct me if I'm wrong but general grievous didn't posses any force abilities, being almost 100% robot, but he still could wipe the floor with any jedi 1v1 or even 1v5 in lightsaber duel. His only weakness was to superb force users like Mace Windu.
So, with the right training and cybernetic enhancements, even if they don't have any force powers, anyone could wield a lightsaber and win against a force user.
On that note, would you allow a character similar to general grievous to play as?
