I feel like the Lee changes are just going to make people not play the champion anymore, and not just because he changed but because he'll just be a great deal worse at what his kit seems to be designed to do and better at something nobody wants.
I mean, they nerfed all of his numbers by a ton across the board and compensated with an attack speed buff on a champion who before really never relied on his autos. SO instead of a slippery, potentially bursty assassin he's now supposed to stick to people and AA them down which I don't think he's going to be able to do.
I don't play Lee but these changes just confuse me. In a metagame filled with unkillable toplanes that just run at people giving no fucks and still doing high damage with minimal damage itemization (Mundo, Shyv, Trundle to an extent) and AP or AD assassins who can delete people at will and get out safely (LeBlanc, Khazix, Zed, Akali) it's just strange to me that they think Lee is the champion they need to hit this hard. Was he really strong early? Yea, but these changes don't really fix that, they just make him worse across the board in every way pretty much.
It won't really matter though. The changes will go through and nobody will touch Lee competitively for months until Riot decides it's time to give him a small buff and he'll stay a niche pick until the end of his days.
