The Crisis reboot was pretty hit and miss, Supes in particular was castrated, although Diana benefit from it plenty, and ultimately since most of the setting was unchanged, it was basically illusion of change for the rest of the main universe... An illusion of change with about a billion contradictions when it comes to stuff like Justice League's story, but hey lol.
Either way it's still not much of a solution, a reboot deletes the past, and that removes the interesting bits too, and again, doesn't work long term with these companies, plus, allowing Marvel to de-age 616 Spidey would, be bad lol.
I also don't see Spidey being allowed to age as a necessary step to improve his stories too, since the problem is editorial and those BND writers lol.
The second point is the biggest problem DC had anyways lol.
Lol, that "Nobody boo" sounds hilarious, when does it happen?
