Listen, Riot is not going to be nerfing Lee, so give it up.
I have played this game for 5 years, and for 5 years the boards have complained incessantly about lee sin and all that he can do. For 5 years, every few months, every circle jerker and his mother comes out to write a post complaining about lee sin, and for 5 years, riot has not given a flying turd donkey about it.
Riot is not going to be taking away his ward hop, removing his execute, reworking his kick, removing his mobility, or dumpstering his ratios, so just stop. Riot loves them some lee sin, and they WANT him to be popular every season. They don't care if you don't like him, they don't care that he's annoying to play in a game with, and they don't care that the solo ranked jg meta is decided by him.
Lee's win rate has rarely been a problem, and he isn't super abusable by pros, so they don't care. So just stop the friggin whining already. It's been 5 years now, it's time to move onto worrying about things Riot might actually do something about.
