So, why is Graves exactly allowed to be grossly overpowered for months?
Let's be honest here, Graves has been top 3 jungle picks since at least Spring split, he's currently sitting at a 21% pickrate, 51.5% pickrate and 40% banrate in Plat+.
Every time I play vs Graves I feel like I'm playing vs a ranged tanky assassin adc that proceeds to snowball out of control if he ever gets a kill. He's good at every stage of the game and he's probably the best jungler to farm with because of his retarded knockback against monsters. Not a weak point in the game, deadly early, strong mid, and very strong late because he's basically an ADC and so he scales pretty hard too.
Are you going to touch him anytime soon? Either reduce his damage/tankiness, or reduce his ability to clear at constant full HP because right now there's no reason to pick other junglers when Graves exists in its current, gross state.
