Here’s a recent post showing hitbox testing https:// i.imgur. com/Z3gJnqr.jpg - you can see it lines up pretty cleanly with the video posted early.
Here’s a dev quote saying that hanzo’s hitboxes are small.
Is it possible that “smallest projectile in the game” actually means “huge log sized” because everything else is even bigger? Yeah I can’t disprove that. It’s also possible that the entire game and netcode has been changed since any of these sources, however unlikely that is.
Unless we get a blue post there’s not much more I can do to try and clarify how this works.
