No i guess not. Cant imagine why you would actually want to chop someone up. But sword duels with unsharpened swords would be cool. Victory would be awarded by marking or landing blows on opponents that are wearing pressure senstive armor. If you take a hit it realeases fake blood.
Could have different fight classes too. Like 2 handed class, single with sheild, multiple combat, dual wielding, japanese katana. In fact isnt fencing a sword duel with rapiers?
