Most of the creators on that series were the creators on the Bat books after. Harper basically rides off into the sunset at the end, and Cass was just brought back to be brought back. They baited people with Robin's anniversary then wasted that entire series on two characters that were ultimately going nowhere by their own hand. They themselves were the ones that went on to ignore Harper. The thought process from the bat office with that series is honestly baffling. They had a platform that could have highlighted or previewed their line going forward, and could have actually celebrate characters that were going to matter, but instead focused on characters they weren't going to do anything with.
