I think the issue people are having is that if two people of equal skill (no matter how good/bad they actually are) are dueling, then the one with no eyesight would lose, hands down, because - well, being blind sucks. That's why most blind people have some kind of aid (a stick, a dog, a friend) when they go walking about outside. They can't anticipate cars, and cars are loud and noisy as hell. How could a blind person realistically anticipate a quiet swordsman? If they were to go flailing ahead, all it would require is for someone to sidestep - and stab. There would be no way for a blind person to anticipate that their opponent would sidestep, especially if they weren't skilled at swordfighting. A sighted person should have the advantage if both parties are of equal skill. But the code doesn't distinguish between sighted people and blind people.
If someone had been RPing their character as an armless swordmaster, I'm sure that would have come under fire immediately as unrealistic and poor RP. It'd still be just as valid as a blind person fighting, however. So...
I have my next character concept.
