My thoughts in general. When Riot goes about making changes to champions that aren't picked/banned a ton, it's a they (Riot) thing. When a champion is picked and banned a lot of the time, it's a community thing. The reason why graves has needed nerfs/adjusts is because he has continued to be a priority pick and ban in both high elo and in competitive play. He has been by far accepted as the best.
And Riot hasn't been giving him what I would call "The Azir Treatment". Azir actually was about 5 straight patches of only nerfs, not even really adjusts. An adjust is a buff and a nerf. All that has happened to graves recently is an adjust on his Q damage and the removal of a mechanic that was never supposed to exist in the first place.
And Riot knows what they want to do with graves. Graves is a carry jungler. Riot's just trying to balance him so that he can remain a carry jungler without being overbearing and without changing his kit. It is when Riot DOES NOT do this that I start to write out forum essays.
Also, they've pinned a post with guidelines to those posting on balance. You should check it out. If you have any ideas or concerns that you genuinely want to be heard, you should voice an actual argument. What are the changes that are "killing" graves? What do you recommend they do? Can you explain your logic and reasoning? I'm not saying you can't post on this kind of stuff. I've made a lot of posts on balance. I'm just saying that you should try to formulate an actual argument if you want to be heard out.
