He also has no hard cc. This is very important, as there's no way to stop an enemy if they try to escape (assuming your laner also doesn't have cc). Unlike Zac, Rek'sai, Lee Sin, Elise, Rengar (conditional), Graves relies on damage to rather than utility to shut down an enemy. Although rengar relies on damage too, Graves relies on it even more. If you are saying that Graves is good because he has 2 escapes, tanky, and is ranged (although range doesn't apply late that much), Riven is twice as good as everything that graves does. And Graves is no longer balanced as an ADC. He is a jungler, because of his autos (which can't reach). Graves has a good kit, I agree. But there's no such thing as a kit or champion without weakness in the game, or they would be getting 60+% winrates.
