Graves is sitting at a 46% winrate, the worst in the jungle.
Riot if you are going to buff him don't buff him towards an ADC, but to the draintank/survivor thing he notoriously once was.
- His damage is weaker the more you move away from him
- speaking of moving away, creeps block his attacks
If you can balance his E mechanic so it's not absurd 180 mr and armor and instead giving him some more damage/utility like his W's slow for instance.
