For me, it’s Graves.
I feel like it bring nothing to the team. He is annoying the first 5 min of the game as a solo laner but that’s it. His damage feels meh, he isn’t very tanky, low range and little utility with the smoke screen.
I never see him win and feels like a ward with a dash and blind.
When Graves gets 6 and your botlane starts a fight. If 1 of them is low enough, he just needs to hit that R and their dead. He has a lot of nasty fucking gank potential especially under tower when diving. The smoke is so annoying bro you just don’t know, the good players know how to bounce that shit.
