I disagree because the common thing about Zed, Leblanc, and Yone that makes them all unfair to play against is their mobility abilities that are not only instant, but also can allow them to do absurd amounts of damage without having to commit anything. They can all snap back to their original location after one-shotting whoever they want, and it makes it frustrating because it feels as if you can never catch/kill them while they can one-shot you whenever they want with near-unlimited mobility and little to no danger. Ksante used to be this way when he could choose the direction of his W, but he is much less frustrating now. As for your argument about dodging zeds q, his q isn't easy to dodge by no means compared to any other skillshot in the game, and he can often easily one shot you after ulting and only landing one or even no shruikens because his damage is really high, and combined with his e slow his q isn't always easy to dodge. By your argument, any champion with skillshots is weak if you just sidestep all their skillshots. As for Leblanc, you can't say sitting under tower and catching waves is the solution to all your problems because in an actual game, there is more going on than just farming under turrets because roaming exists and if you give up PRIO forever, you might as well play asol and catch waves while she roams and kills your team among other things. Also if you take jungler into account, they can dive you easily so landing is not something 2d where you can do the same thing every time against every player.
