Kai'Sa Extreme Kai'sa has a similar problem to Vayne. This time though she has decent mobility and farming. She can get up in your face and bully you out of taking part in fights in the late game.

Vayne Major Vayne is a weird one, sometimes you win hard and sometimes she wins hard. The real problem is that she can just outscale you hard and make it impossible for you to fight her. Because of that I consider her a major threat.

Lucian Even Lucian can either be a free lane, or your biggest counter. I consider this one a skill matchup personally. His biggest advantage over you is his chase potential with his dash+ult. He rely's on winning lane to win out versus Jhin in the late game though, so just don't feed and you're good.

Yasuo Minor Yassuo feels too reliant on his team to assist him in the botlane. He wins early because of his decent damage, dashes and of course windwall. However as long as he doesn't get too many kills early on you can bully him out once you get your first item.
