"I would be worried if he showed up as a prominent pick without a specialized comp built around him"
Gnar has become a staple the exact thing Riot didn't intend or want ** This has nothing to do with if he is OP or not OP, he is far too reliable as a pick as we can see with his almost 100% pickrate in LCS. He needs to be less reliable SINCE IT'S THE ENTIRE POINT OF HIS KIT AND DESIGN!!!**
He has become a staple pick that is safe to use no matter the comp or enemy which means they have made him far too reliable. They specifically stated they made him to be an unreliable pick and that if he ever became reliable that would be Riot's fault and they would have to fix him immediately.
Where are the nerfs Riot?

"I would be worried if he ever showed up as a prominent pick without a specialized team comp built around him. Our pros tend to highly value reliability which is in direct conflict with Gnar's unreliable transformation. If he becomes a staple it likely means he's way more reliable than we intended."
