I'd be fine if they narrowed 'Tec down to Batman, Tim, Steph, and Cass. Kate has her own book. JP and Batwing barely do anything, and there are just too many characters to get really deep into anyone's life.
Tim needs to let the Belfry and Knights idea go, and I think he will. He sounds like Anakin in Star Wars III when he talks about what his plans are. That's not Tim.
