Yes she did. Oracle had plenty of good writers, but she still was just cast doing the same usual things, helping to support others as they move forward and grow, but never actually growing herself or doing something we haven't seen her do before. Especially at time when everybody else around her were embarking on new journeys. Dick became Batman and started taking care of Damian, Tim was forced to become Red Robin, Steph became the new Batgirl, while Babs just made a secondary protagonist in Batgirl rehashing a character arc she should have been well beyond (Her being miserable). And its not like we haven't seen Babs mentor a new Batgirl before. Oracle stopped progressing, and Babs stopped doing new things. Or more accurately DC stopped doing new things with Oracle. Of course a good writer can always bring new life into a character, but DC didn't seem very interested in bringing new life into Oracle. They eventually relaunched BOP, and brought Gail Simone back to do it, but even that was kind of a bloated mess trying to recapture the magic it once had.
