This whole thread sucks and is tl;dr. I've been out of the loop here for too long.
Anyway, here's how it goes: it doesn't matter if Batgirl has the most unique play style in the whole roster and is just superduperextraawesomewithfriesandacoke. The fact is she's a wasted slot because yet another Batman character, and a Batman character that could've just as well been an alternate costume for Batman. Hector Sanchez said at PAX that characters who are similar to existing characters like this would "definitely" be included as alt. costumes for those existing characters.
Well when the fuck is that happening if not with this character? Why does genderswap Batman get her own spot on the roster before Martian Manhunter or Black Manta or Atrocitus or Animal Man or Brainiac or Dr. Fate or Swamp Thing or Mirror Master or any other character that doesn't come out of the Batman canon and doesn't require contrivances to be -made- into something unique because they are actually unique to the roster.
All I'm saying is, I knew I was totally right in thinking that skipping the season pass would be a wise decision and I'm extremely glad I followed my gut.
