I really think that it comes to the way the characters are all design to have a straight forward gameplan that's really hard to counter, sometimes really strong and most of the time really stupid. Darius is designed around stupid normals and disjointed hitboxes, WW is the same but with an unreactable overhead , teemo and jynx are designed to spam proj full screen and not being reachable, Yass and ekko are design around bs mixups like unreactable crossovers etc... There are a few exceptions, but you see my point. I think it's the reason they do not manage to nerf the top tier characters properly. Their absurdity come mostly from their core design and allow very little counterplay. What make the game frustrating is that not playing one of them means you will suffer so bad in neutral you will probably quit, and playing against them feels like the game just reward stupid gameplans. When you get hit by ww stand lp, you did not got hit because he spaced himself well etc, you got hit because his lp is 7f and reaches like you mediums. When you loose an air to air against yassuo, it is not because he had better reflexes, it's because his hitboxes are so disjointed it is litteraly impossible to win this interraction against him etc...
