Huh, I sense a lot of cheating watching that video. Duelling on server when kill depends on scoring 1 lucky hit ain't too interesting.
Native duels works how they works. You don't have any in-game adventage but you can get out-game adventage having nothing to do with personal skills and reflex. In crpg it's totally diffrent (in-game adventage and lesser out-game things influence). I'd love to see a fair duel one day
Be happy for now.
