Jhin
I have seen a few Vids on Jhin, and this champ has too much wave clear. The q bounces 4 times, the trap does aoe damage, and His line shot is a line aoe to over 2000 range. Riot should consider tuning down Jhin's minion damage(why play Ziggs when you can play Jhen).
Jhin's R looks laggy and people have said it is hard to use. IMO the transparent cone used In the Ult needs more style, it should be easier for the enemy to know when they are in the Ult field. Riot should have something like a stylized tree on the ults cone overlay.
Jhin's Ult should have the missing health aspect tuned down a bit to. No one likes the way Garen's Ult works right now, and Jhin has 4 mini Garen ults here....
