Having played ornn for a bit, I've got some thoughts on him.

RIOT PLEASE DON'T BUFF HIM I've been doing fairly well I'm my games as ornn and I think he's petty balanced. He has a pretty healthy kit with clear counterplay. I know his winrates aren't that good at the moment, but I fear his case will resemble taliyah or ivern. Kayn's winrate was complete ass and people were calling for buffs to Shadow Assassin and Caps bust into the room, said 'hold my beer' and wrecked with SA mid. Kayn is in a very good spot at the moment, in a sense of balance. I want ornn to be in this spot, so riot please let players learn him. I don't want this champ to become briefly OP then unviable. Let people learn his combos, his strengths and weaknesses. Keep him balanced.

Also, as a side note, Riot, you've been good at releasing balanced champions lately, many a bit on the weak side upon release. I actually managed to play ornn outside of a blind pick game, and I wasn't first pick! Keep it up, much better than champs like release Camille.
