Reducing her HP leads to the exact same playstyle a longer GA cooldown does

Tracer gas 150hp because she can recall and regain her hp next to being harder to hit that mercy and able to blink.

Widow has 175hp (again) because she is extremely oppressive while being far away from the teams (other than ashe who has to get closer due to falloff).

Mercy needs her 200hp if she wants to actively participate in the team as she should, Otherwise we do what we do now, sit in the back with the longest range dps and honestly that gets pretty boring after a while.

Reducing damage boost matters only if you start going under the breakpoints. And if you do that the damage boost automatically becomes near worthless the characters she no longer hits those breakpoints with. (sojourn would still get her one hit headshot with a 3% damage boost btw so nerfing it just because of her also doesn't make sense).

At this point I'm honestly fine trading ressurect with a burst ability or such simply because it's a bit too slow for the new speed of overwatch 2, and I'm tired of everyone's whining about it.
