I guess that's why Kori might be a better match since she is outside of the IP of Batman. The thing is Batman been there for so long that it would make no sense for Dick to be on JL. Unless he is on his own branch. They need to have a reason for Dick to be on JL. He is in the TT. So unless he and the TT are going to be a new branch of JL. In a sense, we need to have the TT prove themselves even more now too. Dick is generally the leader of the group.
