The smarts of the nobles are mostly in the technological sense, not so much the skill sense, since people like Valcua and a few others are mostly the ones that get this sort of treatment. I also don't remember it being a thing that Nobles usually are using mathetics while they fight to react to their opponent, which is the kind of thing they would need.
But we do have, in volume 1, Doris completely controlling her whip like a living thing, from making the end take a 90 degree turn to the ground after it was reflected back at her with the merest twitch of her wrist, to her ultimate skill where she unwraps the whip in 8 after whipping it, each of the 8 tips perfectly aiming and wrapping around 8 different body parts while each of the 8 tips moves at a completely different speed to confuse the person in question.
And Doris is nothing more than the kid of an Ex-Werewolf hunter that taught her stuff but has never been a hunter herself, and werewolf hunters are more or less trash compared to Vampire Hunters, which are the top of the food chain in the different kinds of hunters in the novel.
Not much, but not worthless.
