Jhin is alot of fun but i feel like his reload time drastically holds him back.
After playing him a few games i really like Jhin hes fun to play and Late game can put out some scary damage and his ult does its job very well.
However every single game i have played him in and seen him played in his drastic reload time just completely and utterly limits his potential.
I have seen Jhins miss kills that any other ADC would have gotten simply because the reload time is so long forcing him to either back off or over commit to get the kill. Its literally the one aspect of his kit i do not like and feel like drastically holds him back from being any semblance of decent. It works on Graves because he hits hard and has his reload speed reduced with attack speed. Jhin doesn't get that instead he gets a crazily overloaded and ridiculously worded passive to make up for it but IMO it doesn't make up for it.
