A few years ago when I was starting out, we still had duel to first blood. I saw a duel to the death on FEI between someone with a sword skill of 70-ish and another with about 65-ish. The 65 won. My oldest character lost his mentor to that duel.
There was also the Atamara Dueling Association. With my sword skill at like 20% I challenged people from 40%-70% to first blood... That was a loooong time ago though.
