Apparently I hit the cap on spoiler blocks in a post (despite it being one long spoiler), but here are the last bits: The worst of the bunch were Bane and Nyssa al Ghul... although technically the worst would be Barbara Keane, if you counted her as a rogue. She was just all over the place in the series. Arguably Selina could be listed as a rogue as well -- since she repeatedly allied herself with rogue groups -- but doing so seems a little weird within the greater context of the series.
There are a few others I'm not even going to bother listing. They didn't really do anything with Grundy as Grundy and prior to that he was just a supporting character. Ventriloquist was neat for all of the ten minutes he was Ventriloquist but, again, what's the point? While I enjoyed his appearance, he was a complete throwaway reference. Most of the mobsters I don't really count as rogues, although Sofia Falcone is a bit of an exception because she was a bit more actively engaged whereas the others felt like they were setting up other characters. Of course, while Sofia was neat, the resolution to her storyline was an absolute mess and -- because she wound up in a coma rather than being killed -- it felt like she was an abandoned plot thread. Barnes/Executioner legitimately fits the role of rogue, but I'm not even sure how to rank him considering his long run as Barnes and brief role as Executioner.
Noticeably absent was Two-Face despite the fact we repeatedly saw Harvey Dent throughout the series. While it would have been neat to see him in No Man's Land/s5, they couldn't really use the characters they had.
