As bad as the Batman family is I'd rather he stay in it than go back to the Titans. The Titans as a franchise has been an unmitigated disaster for nearly 2 decades. Maybe outside of the Johns era team they have been completely irrelevant. The single best thing that happened to Dick as a character in my opinion in the last 25 or so years was becoming a solo character and not having to rely on the Titans. Since it shielded him from their collapse. Branching off from the Titans and even ending his romance from Starfire was the correct move in my opinion given how those characters and franchise imploded. Sure, the Batman family has many issues and I wish things where better there, but it scares me to think about how bad off Dick's character would possibly be if he never became a solo character. He probably would have been killed off like so many of the other original Titans and written out from even more stories.
