My whole deal with Robin is that "Robin" isn't a character identity so much as a role that serves Batman. Whereas other characters can temporarily take on the role of "Batman", it always returns to Bruce Wayne. Robin is a transitional role for a young hero to move on from... resulting in ever-increasing redundancy rather than uniqueness. Dick Grayson successfully becomes Nightwing, Jason Todd eventually becomes Red Hood(bad name), Tim Drake, Red Robin(?) is currently in limbo. And what does Damian Wayne have to look forward to once a writer decides he wants to come up with a newer better Robin?
IF Robin is just a role, I felt the We Are Robin title was genius. Everyone young becomes Robin. Everyone works to fight crime as a grassroots movement. Sadly, it fell apart before making any real waves in the Batcave.
If were up to me, Dick Grayson would never have retired the name Robin, and rather had the name mature along with him. Subsequent sidekicks of Batman would've taken on other names that they could own and mature with as well. We never would've gotten We Are Robin, but that's ok. We would've had something else.
