So Jhin has a 52% winrate......with a 35% playrate
we can complain about Caitlyn's 50% winrate on a 20% playrate but the moment you raise a finger against Jhin a flood of mains rise against you babbling about counterplay and windows of power? "oh he's so fun to play and his kit is so in-depth and beautiful" no, he is a pain to play against and pretty blatantly overtuned
yes, I understand an assassin can jump an ADC. That is not adequate counterplay to the crit-pen monstrosity that is an absolute beast from range while also being one of the most potent kiters in the game. He's been the number one ADC in the game patch after patch, pick-ban in the LCS, and has maintained a strong winrate with a bloated playrate in every meta since release. Meaningful nerfs are in order....
.....and a 1-second reduction to the combined 3 second slow on his ult, which he shouldn't even have in the first place, won't hurt him in the slightest
and before people yell BUT MF BUT TWITCH BUT QUINN yes those champs are also overtuned and annoying, but they have fractions of fractions of Jhin's playrate. Jhin is the Lee of bot lane. If you took away all the noobs and wannabes playing him you'd see how disgusting he really is.
EDIT: op.gg, which Riot themselves have said is more accurate, clock Jhin in at a fucking 54% pickrate
is my bane as Jhin, FLAT counter. Not saying take him ADC but if a xin ganks me or catches jhin out he is in trouble
