Jinx doesn't need nerfs. Her counters need buffs.
Jinx has hardly received any changes this season, but her counters like corki and lucian have both been nerfed. Her meta presence right now is only due to her early game counters being nerfed to the point where she can consistently get past the laning phase into her strong mid game. The reason she became so prominent this patch was because pretty much every other top ADC got nerfed within the last 2 or 3 patches.
I counter her. With my Arrow. To her knee.
I counter her. Shove it up her short shorts.
I counter her. With my overbearing hotness. Also I press R.

, who before his rework, was considered the number 1 counter to Jinx in bot lane. You wanna know how often Jinx won that awful matchup? 52% of the time. She may not be as strong now as she was then, but the concept is the same. Her only "bad" matchup is MF, and even champs that you would expect to do well against Jinx like Jhin and Draven still do badly against her. She's OP. She has meaningful, exploitable weaknesses, but she's still OP. And honestly, I'm ok with that. Some adc has to be OP and I'd rather it be Jinx than most other adcs. Remember when Vayne was the best adc for a few months last season?
buff would be ok, but I'm not too familiar with her winrate as of now to back my opinion up.
's getting buffed this patch. Possibly next patches too (Which I fear will make him OP enough to be forced to nerf him and make him useless again)
