It looks like Roadhog can still one-shot kill with his hook in Overwatch 2, actually

It appears that Roadhog’s one-shot kill hook combo is still alive in Overwatch 2, despite a hefty nerf in a recent patch.

Yesterday’s OW2 update nerfed Roadhog’s ability to easily land one-shot kills on squishy heroes, or so many players thought. The balance patch reduced the impact damage of his hook while also nerfing the damage of his Scrap Gun in an attempt to heavily reduce his one-shot kill potential.
