PSA: Jhin hasn't even been released yet
Jhin hasn't been released yet, so we DON'T know how he scales, what he EXACTLY does with his kit, and how he plays; we can only theory craft. So hold off on your "Jhin's kit looks dumb etc etc" and just wait until he is actually playable on the PBE and watch Youtube videos on him.
{{summoner:2}} what you did there
at level 14. My friend was playing him and he was astounded by the sheer damage he dealt in extremely short amounts of time.
