Rebooting 52 titles simultaneously, and having Justice League be your flagship comic, seems like a way to completely undermine all the possibilities a reboot offers, except the purely financial ones. Wouldn't you want to let your superheroes muddle through alone in a simpler plot arc for awhile, before bringing them all together. Wouldn't you want the Justice League to be something that happened slowly, as the superheroes meet each other over time? I get that endless retellings of each superhero's origin stories get boring quickly, but that's different than "just how did Superman and Wonder Woman team up..." type stories which seem to offer more possibilities.
