At the time it did seem like Bunn didn't want that cast. The question he was asked in his interview was about Uncanny and he had said he had all these plans and then the office said they were cancelling the book and offered him the O5 cast for a new book.
In essence this isn't the team he would have chosen especially since it's already a set team.
It's annoying that Warren & Bobby aren't given more. They're falling into the same traps as the first go round with their story lines. Bunn's even said "i have something for them later on" but meanwhile Jimmy, Bloodstorm, those "Puck" followers and various alt. reality gimmicks all get meatier portions of the story.
