A filler episode is not one with no ties with the other episodes. All of that which you pointed out are minor details that wouldn't hinder the storytelling by leaving them out. Klarion for example didn't need to to have an episode to introduce him. He might as well been introduced in "Revelation" just like most members of the Light and then reappear in "Insecurity". As for 2, 3, 4, 5, your points are all trite.
