Yes the 1st issue seemed to give the game away.
Agreed so long as they keep using him the way they currently are then everything's fine. Damian doesn't need to be Bruce's son to be Robin or to lead the Titans or to have the amazing dynamics he has with practically everyone. That's all just Damian.
However it does ruin the whole concept of Batman Reborn and the entire meaning of what Morrison was trying to achieve [wonder how Morrison feels about that] It changes Damian. at times it feels like DC likes to destroy what their fans like.
Look at Tim. They've changed him beyond recognition.
Honestly looking at the hack job they did on Tim I would not put anything past DC.
