Also I don't even know why Volfe Karkko carries a lightsaber. He's so bad he makes me want to stick my finger through my head and into my brain and twirl it around 360 degrees.
I disagree. Remember Plagueis hated lightsabre duelling. Palpatine believed that the Sith didn't really need lightsabres but they were still worth using as a way to mock the Jedi so had at least some investment in duelling skill. Plagueis had no interest in it at all.

Beg your pardon but so what? You can have "perfect form" and get beaten by some goon in a pub that only cares about winning. Dooku says this in "Labyrinth of Evil" and he's absolutely right.
Having "perfect form" is great for scoring points in a tournament but by itself it doesn't mean much in a real fight.
So clearly he's a skilled duelist, who's completely mastered his chosen form. Ok, I'll humor you and say that maybe he actually wasn't a stellar combatant. But one of the worst duelists of all time? No.
I'm pretty sure it does actually. I'm pretty sure that skills in the use of a lightsaber pretty directly translate into being good in a fight. You know, since lightsaber techniques are kind of meant to be used in a fight. That's what they were literally developed for. It's like saying that a guy who's a fully trained marksman wouldn't be a good shot. I'm pretty damn sure that he would be. That's almost a redundant sentence because that's the same thing. And Farfalla isn't some teacher who learned karate in his spare time. He's a Jedi Master who lived through an actual war with the Sith where he fought on the front lines. I'd be confident in saying that he's likely got more real experience dueling Sith than every member of the PT Jedi council combined. Your point is further invalid because you're coming from an example where the guy isn't literally a superpowered martial arts monk. People might be shit in a real fight because they're physically impotent or they don't handle stress well or make good decisions. But like I said, Farfalla is a Jedi Master. He's in the peak of physical fitness, he can augment his physical attributes, he has enhanced senses, he can allow the Force to direct his actions, he has precognition etc.
Also since Farfalla's style is highlighted as graceful, I think its most likely he was a Makashi duelist.
IIRC Thanaton was getting torn up by Kressh's niece, and Kas'im getting driven back by Bane who was far less skilled, having to cheat and sabotage Bane's training make him look terrible as a duelist.

Not sure how you think Bane was far less skilled than Kas'im. The text directly says that Bane was able to counter him whenever he tried to change tactics and that there was nothing Kas'im could pull out that Bane didn't know how to deal with (barring dual wielding obviously). Bane's upper hand was just as much a result of his skill as it was his superior power.
