Leona

Honestly I have much to say. Really annoying support. She is too tanky for you to take her down early, she can deny you from farm as she will stay frontline and jump with E Q whenever possible. Be extremely aware at lvl6 as she will most likely almost insta engage with R > E > Q. The only way you can escape is if you flash her ult. You really depend on your support to help you out on lane and try to throw a few Q's and autos at her.

Nautilus

He is quite a big deal. He is too tanky and has too much CC. Similar to Leona he will look on opportunities to throw his Q on you whenever possible. Try to stay behind minions. You can poke him behind your wave.

Xayah

Major threat. Attack speed counters Jhin. Don't even think of a 1v1 with her. Watch her feathers in lane and move around, don't stay in one place. Sometimes you will have to flash her R because she can engage with that and root you and take half of your healthbar. Wait for your Rapidfire range boost.

Tristana

A really good Tristana can ruin your day. If you get stunned or don't keep your range, she will all-in you and kill you, because of her E burst and Q attack speed.

Lucian

Hard lane. He can burst you pretty easy and can dodge your W and you have no way of escaping his R. Farm on lane and try to hit him with Q and 4th's.

Varus

He can be quite the bother. He can poke as much as you. Also you have no way of dodging his R. If you get hit by it you are screwed, its really hard to escape even after the ult ends.

Jinx

She can be a threat sometimes if she pairs up with a Leona or a Lux / Morgana as she can chain the CC with her E.

Draven

If you are not careful and die early you can lose the lane, It depends on how good he is. Keep your distance and poke, also its worth taking Executioner if he rushes Bloodthrister.

Ezreal

Sivir

Caitlyn

Miss Fortune

Kai'Sa

I find it mostly easy to lane against her, your trade is better, keep on poking her and you win the lane. She is quite bad if she doesn't farm in lane and is behind with items.

Twitch

Easy lane. He has poor early and needs items to be useful. Keep poking him on lane.
