ill give first a small talk about jhin reason why i like this champ is just of his execute style and power to punish your foes for making a mistake at the same time you get punished hard if you make a mistake jhins early is abit weak compared to others so i would reccomend him with a supp that can some peeling like annie zyra sona morgana and lux they go great with him others work well ofc but this champ early goes much easyer if your supp gives you nice peels and get them prepped for your 4th shot or set em up for your w and then follow up combo anyway his early i always focus on the farm until the supp makes the play and asoon you hit lvl 6 thats when you can shine and open fights or mop up the left overs from a tf the enemy lost anyway lets get started

so since jhin only got 4 shots lats hitting is key and when you reload hit the lowest hp minion with your q if it kills it you might can get a few more cs

pros

alot of dmg per aa
4th shot can kill almost anyone on the right percentage
ult can provide vision has alot of range and provide slows for the team

cons

early is abit weak
very support depended
no escape abilities
lacks power to melt towers
sometimes cant melt a megatank
