Stop saying zed has no counterplay
I get that he has insane kill potential after lvl 6 and it can feel pretty unfair to play against, however there are still ways to counter him. Most of the matchups that favor him are mages, which can easily deal with him if you don't mind a boring first 10-15 mins. Though it might seem shitty all you really have to do is just give up almost all of your lane dominance. Once he hits 6 you sit back and farm with abilities or wait for the wave to get to your tower. Deny his ability to make good roams by making sure to prioritize vision, ping whenever he goes missing even if you aren't sure he actually left, and hard push the wave every time he leaves. You are essentially starving him of a snowball by making sure he doesn't get any kills. Plus, at lower elos at least, the zed will probably get bored/annoyed because he cant fight you and he might try to dive you which can result as an easy kill if you play it right. Do this until you have enough for a zhonyas then try to roam and use your utility as a mage to peel for allies and get picks. That's just for mages, but most assassins have a pretty easy time against him. Champs like yasuo, Kat, and ekko can beat him with relative ease unless the zed is playing better than them.
Edit: Im pretty sure most people aren't even reading the post, they just see someone that SLIGHTLY sides with zed not being gutted and they just have to downvote it and move on. :/
