Look, I GET that it's impossible to please everyone, because obviously, everyone has different tastes. If Tim, Cass, and Steph got their team book, who knows, maybe die hard Batwing fans would resent them.
I've gone over before how every major Batfam member could be included in an equally spaced book, while still keeping the total number of Batbooks under 10. There IS a way to give the fans of ALL these characters a decent amount of time with them each month.
I don't resent Violet, no. 1) Because she's not Batfamily, 2) Because from what I've heard she's got an interesting personality and backstory, and 3) Because up until just now, since I pay very little attention to Young Animal, I didn't even realize she was a Gotham based character.
