If a big fight scene suddenly looks dim, blurry, or choppy while watching a weekly episode, the animators are usually not the problem.
TV broadcast rules in Japan force studios to dim flashing lights and blur fast scenes so people do not get seizures. On top of that, studios are rushing to meet strict weekly TV deadlines.
The real, finished version usually comes out later on the Blu-ray. That is where they remove the dark filters, clean up the motion, and fix messy drawings. If a scene looked weak on your screen, TV broadcast rules were probably the reason.
Did you know about this, or did you think the animation was just bad?
