Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Jhin is unarguably one of the strongest AD Carry in the current meta. Jhin took a major part in my ranked wins, climbing from silver to diamond in one season.
I felt that the guides online are lacking in information for players who desires to try out Jhin therefore I made one myself. Although I do not have the time to finish off my Jhin guide, feel free to ask about the game plays, why the runes/item builds are strong or any other things you want to know about Jhin in the comment section. I will try my best to reply on most of the comments and help you guys out. :)
