Stop asking for thresh nerfs
He completely oozes counterplay, and IS a jack-of-all-trades master-of-none. Now you compare to Blitzcrank, who literally zones you by existing, has an instant-cast hook which is 4x more toxic than Thresh's. Now everyone is up in arms over Janna nerfs, and while disengage is her thing, she's doing it a bit too well.
It also seems the basis of a lot of justification for nerfing is his pick rate (in no relevance to his win rate) to which I have 2 things to say: Is nerfing a champion based on pick rate ALONE okay? And 2: he is a support. The reason why this matters to me is because support is usually not exactly a contested role, so for those who don't play it, they'll most likely buy and use what everyone else is using.
Now it wouldn't exactly take long for someone to find me being salty about Lee sin, for somewhat the same reasons, but here is the difference to me (which should be the only problem since it's my bias to begin with), when Thresh escapes from a poor misposition in our jungle, I usually think, "wow, that was a pretty sick escape", whereas with Lee Sin, I think "why did I even bother...". (IE, thresh can be punished and Lee can't)
TL;DR, thresh is significantly better than both his hook counterparts (Naut and his fat-ass hitbox into never ending cc-chaining, and Blitz who zones you by moving forward) as he has much more counterplay, and while he has a lot in his kit, there's always a support that can perform 1 or 2 things he does but better.
