Getting Rank 5 Mastery....

You know that's why you don't purchase Jhin You can only be a true Jhin main If you only play him when he's free this works because If you do not own the champion you can only get up to mastery 4

Every jhin player needs level 5 mastery.

It's a horrible time when a Jhin player reaches the point where his next match, win or lose, will take him to level five mastery on Jhin. Because at that point they must now face the fact that if they are a true Jhin player they can nolonger play Jhin without losing level four mastery.
