Nerfing in general

Hello fellow players I am gonna describe an unpleasant game expirience I just had.So I was playing Jhin(Viva la 4)evenn though he is even in current meta I still loved him I was fed and I had the unplesant pleasure of playing against a fed Maokai.So I bought a grievious wounds to reduce his healing from his passive but that didnt do the trick.His passive with a spirit visage which boosts te healing capabilities plus the cdr made him unkillable.I mean I was bringing him near to death and he was just using his passive and he was always getting a lot of hp back.I felt so hopeless against him it was such an upleasant exprience so please maybbe nerf his passive??And I wanna talk about an other thing that all of lee mains will agree when you removed trackers knife you made lee kinda hard to play but not even him anyways.When you removed that item lee sin after alll this nerf and then the final blow with that remove I think you made him unplayable maybe add an item or change the w of lee just saying.Isnt worth to purchase control wards for the money tthey cost plus the space the occupy.The other solution is to go for a support item but its kinda useless since it occupy a space also therefore you make lee sin mains to be in despair or forcing them to buy items they dont need in order to be effective in ganks wwith their w.Thats all folks....
