Waid is acting out of ego.
There's no need to do a reboot, but he wants to do one or otherwise he'll miss his made up 20 year deadline.
And just because you have a hard time accepting that concepts like super pets were created to make the comics more interesting to idiots doesn't make me a moron.
You actually must think that super pets were created because of the medium, that because it's "comic books" such concepts HAVE to be part of it.
