They just need to rectify the horrible Batgirl (seriously Barbara Gordon in a fighting game?) with the RIGHT Batgirl (Cassandra) and Batwoman. But that's NEVER gonna happen with the current regime at DC.
of course not... but if they want to start adding characters that have been introduced into the mythos of the game universe (ie the comic) they just need to do skins for Batwoman/Huntress...
