Riot, don't kill Kayn.
For the first time in a while, I am excited fro a champ and am actively grinding now to get the IP for him day one. But at this state I'm scured he will die in PBE. First 24 hours he was on PBE, hundreds o0f videos we're made with "MOST OP JUNGLER - MY MOM HUNG ME AFTER THIS ONE" and, much like new champs have died before, he'll be nerfed into a darkin beef sandwich before he hits live. And to those making threads and such about how OP he is whenever you don't have a PBE account, wait till he hits live before flooding RITO with cries of the nerf hammer.
