Yorick was reworked for having an "anti-fun" kit
Teemo has fit this damn catagory for years. Teemo is a meme at this point yes. but you dont smile when you see one on the enemy team. you dont just sit there and look at it as every other champ. no. every time there is a teemo on the enemy team you groan because its one of the most annoying things to play against in the game.
He has an Anti-Fun Kit and if you talk to anyone long enough they will agree that its cancer. Just like old yorick its not OP. otherwise it would be played in every match, but it doesnt have to be OP to make you want to hang yourself every time you see one on the enemy team. Near Yorick's rework they actually REMOVED him from a free rotation because they felt he had a negative impact on the enjoyment of the games that he was in. Teemo time and time again shows that he completely fits the anti-fun catagory due to the insane simplicity of the kit and the lack of a way to play against it.
The problem with Simplistic kits like Teemo and Old Yorick is that they arent strong. They are just so damn passive kits that while they arent the strongest things in the game. there isnt really a counterplay to them. Lets take a look at Ahri who is considered top tier atm. She is strong. very strong. But if you are a semi mobile champ you can play around her abilities by dodging them. Compare this to Old Yorick and teemo. You cant play around them. While they dont have the power of the Ahri kit. They have a lack of counterplay to them.
TLDR: Teemo is cancer. Needs a rework that makes him stronger, but adds counterplay to him.
