that doesnt make sense one bit, where do you think the lore comes from?
cartoons comics books and films. but films also have to have sepcial rules , it might be ok to let han fight a sith and win in a film tho it would never happen in the "real" canon of lore.
like this game all troopers smugglers agents and bounty hunters are as powerful as jedi/sith which is complete and utter tosh lore wise but because in a game balance > lore thats the way it has to be
