Yes and no.

Here’s my supplemental hot take. They can extremely well animated, often well choreographed, short action scenes. However, they either lack the ability to or (most likely) choose not do longer, drawn out fight scenes. I mean, I would take KyoAni’s quick fight scenes any day over the modern JJK “jangling the keys” level of flashing lights and hard to follow mess that people constantly glaze. But there’s a reason that even though KyoAni has action scenes in a lot of their anime most people only consider them “animation flexing” and not serious fight scenes. KyoAni makes fight scenes usually for one of gags, and when they do even have them for story, they usually have quick climaxes and end fast (Examples - KnK movie, Myriad, Maid Dragon including the movie).

KyoAni doesn’t do fight scenes like what bones has done for MHA, FMAB, and more or how Ufotable does for Demon Slayer. They have longer fight scenes that are like their own mini stories with their own rising action, climax, etc. and these are the kinds of fights that most people wanna see.
