It's honestly sad to see the amount of hate against Zed here on these boards.
Ever wonder why Zed has such a high banrate despite being in an alright but not overpowered state?
Because people just hate playing against him as a champion. They're not used to assassins actually having decent poke and some waveclear (although little might be the better adjective here to describe the amount of waveclear he has against mages)
For this reason, people ban him. However, what they are missing when banning him is the question of why assassins aren't allowed to be good in the laning phase against mages (let's face it, Zed is pretty weak in the laning phase due to his lack of waveclear, and waveclear is meta right now. If a mage player has to constantly back against a Zed they're likely doing something wrong such as dodging none of Zed's WEQ combos).
Also keep in mind that it's mainly the lower elos that ban Zed. Up in the higher elos, there is a significantly smaller portion of players banning out Zed. Those who still do are (you guessed it!) players that main mages in the midlane along with ADC players.
Part of this can be attributed to the fact that players have adapted to laning against Zed. In lower elos, where mechanical skill and knowledge of lane matchups is not there, Zed will likely be a much stronger pick due to his all in potential.
With all this information, it should come across as no suprise that Zed is a universally hated champion, but those who hate him have little reason for doing so. It's really the fact that they haven't learned to play against him, which is upsetting because they have no other reason of hating him. If Zed were in a stronger state or actually had the access to this midlane-defining aspect of the meta called waveclear, then maybe the hate against him would be understandable. However, by no means is he as strong as midlaners currently are (wonder why there has been literally zero Zed games throughout this competitive season?)
Edit: Here are my sources for banrates being lower in high elo and higher in low elo not sure if they were entirely reliable, but still. https://www.leagueofgraphs.com/champions/stats/zed/bronze https://www.leagueofgraphs.com/champions/stats/zed/diamond
