Starfire's solo did well enough, and she is a popular character thanks to the 2003 TT series. If DC actually embraced what fans liked about the OG series and managed to make it work as a comic or hell if they just rebooted the whole series and continued with a new season, I can guarantee you it would be a success. I still see a lot of fanart, fanfiction and edits of the series, something I can't say about most of DC's franchise. I don't even care who Dick ends up with because I don't care much about romance, but let's not pretend there isn't potential with Starfire and the OG Titans (from the show). It also would be great if we could stop the whole Babs vs. Starfire thing, they are both good characters and can exist and be in the spotlight at the same time.
