Hawkeye will always be strong barring a complete rework

The nerfs didn't address the fundamental problem with Hawkeye: one shots.

He is the only character in the game that can one shot opponents without ultimate. This means it is currently the only way to supersede the game's extremely high healing.

Nerfing his damage slightly won't matter. As long as he is able to deal over 275 health in a single arrow, he will remain strong.

Hawkeye can control extremely large areas just by existing, because the risk that you could get domed by an arrow and dropped without even being able to see the enemy Hawkeye is always present, and for the vast majority of characters, there is no counterplay aside from standing behind cover and hoping your divers can do something.

Until Hawkeye can no longer one shot squishies, he will remain strong.
