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.
I’m only diamond but every bard I see is basically a guaranteed loss. I hear he’s better in Proplay (although almost never picked) and Apex tiers due to teams knowing how to use his portals to more rapidly rotate/collapse on ganks.
