Corrected entry: Rochefort is wearing an eyepatch, which means he has no stereoscopic vision. It's hard to imagine that he could be any good at swordplay because he is not able to determine distances of objects, especially fast moving swords.

Correction: Sorry to disappoint you, but there have been historical records of one-eyed swordsmen and even one-eyed archers. Apparently, with enough practice and instinct you can make up for the loss of three-dimensional vision.
