Actually I think she got much more focus than ever in trinity or jla themed cartoons. I can't really blame the creators, they know the fans want the best villains and rather watch 100 luthor-darkseid-etc episode than some guy they don't know. At least Circe was great, the playful sorceress angle was very good, she was capable and I personally loved the way she was defeated.
As for the rest of her villains, maybe next season, r-right? Right?
