Problems with the champions.
Kai'sa 28% pick rate. Thresh 26% pick rate. Lee sin 25% pick rate. Lucian 24% pick rate. Graves 21% pick rate. Jhin 21% pick rate. Yasuo 19% pick rate.
Yasuo 58% ban rate. Akali 54% ban rate. Zed 51% ban rate. Darius 49% ban rate. Irelia 43% ban rate
So ... only Yasuo and Lee are picked because of popularity, the rest is broken. Can we do something about it?
Also, ban rates. Those champions are banned because they are toxic. Their playstyles are so toxic that more than 40% of people ban them, which is insane. They need to be changed or nerfed for us to be able to even play them.
Buffing Darius was a mistake, he is actually unplayable now. Literally. We cannot play him. He is banned.
Irelia is broken. Everybody knows that. Nerfing them wouldn't actually throw her out of meta, but we would be able to play her at least.
Zed should be fully reworked or lethality should be reworked. He is oneshoting with only dirk. 51% ban rate is a joke.
Akali is broken. That shroud is too toxic and strong. Not being able to see or fight something that is killing you is too much and ... 54% ban rate ...
Yasuo has 58% ban rate. Nerf him or rework him. He isn't broken, he is just toxic. 58% makes him unplayable. I literally don't see him in ranked. He is always banned.
Ban rates are telling us that something is not right with some champions. That people don't want to play against them for some reason. Let's act upon that information.
Pick rates are telling us that some champions are too popular for some reasons. Yasuo and Lee are fun to play so they are picked often. Also reworking them might be bad. If they are so fun to play, reworking might destroy that.
The rest of champions that are picked too often are:
Graves - he is broken the whole season and people are bored of him. He needs to be off of meta.
Jhin - his movement speed and dmg are too high. It actually makes people play him incorrectly and still win. Also, this playstyle is easy to play and strong. His pickrate doesn't resemble his popularity, but only how strong he is.
Lucian - the 2nd strongest adc at the moment and too flexible, safe and dominant. He can actually carry alone. Items for adc are too ... not for adc. Those items must be changed.
Kai'sa - pick or ban. Literally broken. Everybody wants her on team. At least isn't broken the whole season like Graves, but she also must be nerfed a little bit.
Thresh - I actually don't know why he is this strong. His pickrate doesn't show his popularity. Maybe he is picked so often because Lucian and Thresh are good together. That would actually explain a lot.
Riot needs to adress those issues. In S5 there were 4-5 toxic champions. Now it is like ... almost every champion FEELS toxic.
