The New 52, Corrected: WildC.A.T.s
What Happened: This replaces Phantom Stranger.
What I'd Change: Hit the ground running. The Grifter and Voodoo comics made it fairly obvious the Daemonites were invading. The WildC.A.T.s would be the only superhero team on Earth who knew about them, and the only ones capable of fighting them without being taken over in some way, shape or form. Start with the full team and have them kicking ass out the gate, and doing their best not to alert Earth that MORE aliens have come to Earth.
Why: Because some characters are team characters, and Grifter and Voodoo are some of those kind of characters. You've got Helspont fighting Superman? Who was asking for that? Nobody. Stop that. Let's get the Kherubim and half-Kherubim soldiers out there on the field, WildStorm's premiere superteam (to me at least) should have been one of the first to get a comic, not freaking Stormwatch.
