I mean obviously Riot recognizes him as the massively popular champ he is.
A Halloween skin could either be awful or the greatest shit.
Candy Kayn I don't want though. Pun skins are generally awful.
PROJECT would be super generic but I'd buy it anyway.
Still plenty of time this year to see a Kayn skin and he's undoubtedly going to sell them. The only innate problem is the work involved for such a skin.
