Yeah but I don't really see much compelling evidence that the Golden age villains in particular have no need to be revamped and she benefits from ignoring them
Not when her core rogues gallery is still Cheetah, Ares and his cohorts, Circe and Dr. Psycho, all golden ages villains who were revamped and still have recognizable roots in their old portrayals. Whereas a lot of villains from the 90s and 2000s have fallen by the wayside. Stands to reason that other villains from that era could use more regular usage as Marston and his team put more thought into their villains than others if that period.
