I honestly don't get this argument. Heroes usually face threats relative to their power levels. If you are reading stuff like Toriko or Dragon Ball, then the villains will also be Planetary or beyond and the heroes in these series receive far worse beatings and injuries than I've ever seen Wonder Woman get in any of her comics. You don't need to nerf your character to challenge them.

Nerfing Wonder woman literally leads to nerfing her villains. Just look at Sensation and the street level stuff going on over there.

The only time Wonder Woman is ever gonna breeze through villains is if she is somehow set up against weak opponents for some ridiculous reason.
