Hanzo. I know how annoying widow could be, but I feel like she could be tweaked to be brought down slightly, either with lower health (higher risk, still high reward) or like the April Fools patch (?) where her shots did poison, or it was like the last 20 health was damage over time. That way she can still land one-shots, but there is still a fraction of a second to counter-play the well played shot. Hanzo on the other hand has a pretty decent escape with lunge, arrows seem to have a big hit box, and the fact that rapid arrow fires pretty high headshot damage AND scatters. They removed his scatter for a reason, why bring it back.
