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.
As much as I love her, Renata Glasc. Her kit feels like has far too much downtime where you do nothing, and what she’s able to do doesn’t feel impactful enough. She’s an ult bot, and even then, the enemy team can completely build to dampen her ultimate. She’s got a great characterization, and landing her ult is fun, but the rest of her kit just feels like you wait too long to do nothing.
