BnHA is first and foremost about Deku's journey, and while many of the villains can be interesting, they're interesting as foils, not on their own. The readers enjoyed tournament, training, Hero Killer, and all the other arcs because the heroes were involved. Tomura is a boring villain, these new villains are too new and have nothing invested into them, and too much of this feels irrelevant to the main plot. If this were a spin-off specifically about villains, that'd be one thing, but over focusing on the villains in the main story is annoying. This arc needs to end real quick or integrate the main cast.
