The problem is not “X” hero is broken&overpowered the main issue is the DEV-TEAM let the hero being broken months or years saying “Oh no the hero is perfectly fine” dont need adjustments when the player base is ASKING for adjustments everyday.
The way of nerf OP heros in my opinion is keeping their “Force” but asking the players even more “Mechanicals”. example.
Giving Genji 150HP but in exchange give back the 3 jump of the beta, reverting his dragon blade duration back etc.
Giving to doomfist 200HP with the adjustments will hit the PTR the 19 march.
Removing the ability of Head-shot tracer guns to make the player workout more her kills and revert her “BOMB-DMG” nerf for example.
Zeny giving back to him 150HP but add a teleport ability similar to moira every 6 secs to make him harder to kill
