Great article and I think that W3 pretty much nailed Sword-Fighting compared to any game atm. To date - IMO it's the best sword-fighting combat game.
However I really liked this comment from a random dude in that article's comment section.
"If you're talking about realism of the sword fighting in this game, you are dead wrong if you are saying: "no matter how good a swordsman you are, fighting a coordinated group of opponents will almost certainly end up with you dead". You said it yourself in previous sentence that it's hard to imagine sword fighting with a creature that doesn't exist, yet you contradict yourself by focusing on how Geralt does sword fighting. Geralt is not a human, a witcher, something that also doesn't exist, so why he should do a realistic sword fighting as a human does?
Have you met Hjalmar in Undvik while playing the game? He said that his father often tell about how great the white wolf is when he was small, now he met Geralt when he is already an adult. Practically, Geralt is a living legend, his sword fighting would be unparalleled, can be full of flashy moves if he want to.
Have you seen the witcher 1 trailer where Geralt practice swords by the bonfire where at the end of the trailer he was fighting with pack of wolves? Do you think that moves is human? No, cause he is a witcher.
If you want to talk about realistic sword fight in this game, you shouldn't focus on Geralt, but focus on those Guards, Bandits, Pirates, etc. Look at how their movement whilst holding their swords, shields, clubs, etc. For me the way they behave is pretty real. If you're saying that Geralt moves is too inhuman, cause he is inhuman. It's like saying there is no way a human can move like Spiderman, well duh, he is a mutated superhero. "
