Firstable i was always saying Wraith is a OP legend, but right now she is in a good spot, and should not be nerfed more. She doesn`t need buff, and she doesn`t need more nerfs for sure.
She is okay as of now and can do her purpose in the game.
If you just put aside your bias, and think for the overall variety and balance of the game, you can actually see the idea of respawn with the different hitboxes now. We got a tank, that is harder to go down, but he is easy to hit, we have a dodger in the face of the Wraith, which is very hard to hit, because of the small hitbox and her animation movement.
Pathfinder is the mobility guy Wattson is for camping and barricade, Caustic is useful for certain situations as well.
And we have a tiers, but with no OP legends as of now, only Mirage and Octane is in a bad spot, esp. competitive.
Tho i feel for you i think the nerfs for the Wraith is over.
