Riot, you've really done it this time! (Also small rant)
After 7.17, there have been so many bugs with Ornn. I knew that Ornn was revealed (or teased) a bit too early after Kayn's release for some reason. Now I know. He is unfinished. I say you just disable him and fix all ur stuff and release him when he's ready.
And here is the rant- Riot, what is your EXCUSE for the Nasus buffs in 7.15? I see what you were trying to do, but here is why you went about the changes in the completely wrong direction.
I'd consider level 6 to be still relatively early game, so the fact that as soon as he hits 6, no matter who i'm playing I can't kill him again is a bit stupid. I feel like at the very least make it like a 20/35/50% decreased cooldown on his ult to really make him good late game and still make it POSSIBLE to fight him in lane? Also, You want him to be better against tanks? Fine, make his Q do %Max Health damage or something.
I know i'm a bit late to complain but I've been against WAY too many Nasus's and haven't won ONE lane just because of this change, it just feels impossible.
