PSA: Cho'Gath is OP
GASP A character with no snazzy mobility LCS play options and an outdated 1 skill per slot movepool OP?!?!? Impossible!
I promise you though this character will become FOTM very soon and will absolutely be getting nerfed/re-worked sometime in the near future. His base damages and AP ratios are absurdly high along with very good base stats and scaling across the board. Combined with the fact that he almost gets an entire warmog's armor for free and you truly do have a terror of the void.
Just think I'm salty after losing to a Cho? He's actually my most played champ.
Have fun and enjoy your freelo before he becomes perma-banned and nerfed.
P.S. I literally just follow this guide: http://www.solomid.net/guide/view/120517-chogath-build-guide-apc-jungle-fighter-by-jiggaflip
