Wasting abilities on clone guessing feels bad

Pretty much title. LB's passive, shaco, whoever else. There is extremely little skill input you either guess right or you don't. Why is this healthy or fun for the opponent? I don't know much about the new champ but the trailer already made me hate her with that "lol fake hec u guessed wrong" idiocy. Meh im silver 5 so maybe im just bad. Well i mean i am, but at least for most the cancer champs people complain about in the game you can learn to play against them. Their is no learning to a 50/50 guess, or the 33% chance to guess right I saw in that trailer, and that's all it was a guess. Which makes for a garbage experience in my humble opinion, which I hold regardless of the new champ, it's just that seeing it triggered me.
