Jihn counters?

Stay at your fountain and stack armor.

He deals a lot of damage, yes, But he's also quite squishy with little mobility. So if you can get to him, you can kill him. So i think a assassin or burst champ would counter him.

Anything with decent mobility or CC.

kassadin, play extremely safe early, when laning phase is done and youre about 1/3 of his farm you can start to punish him HARD.

He is pretty slow, and I feel like anyone with a gapcloser and sustained damage or high burst would deal with him.

Twitch would probably be good.

yasuo counters jihn hard late game because yasuo has high crit so he does lots of burst damage, his e is a gap closer and his w blocks ur ult and other moves.

ive found kalista does pretty well against him. really mobile to dodge all his spells
