I don't think it's ever been there. The Paragon Heroes and Rogue Isles Villains have always been there, and they include many of the Rogues Gallery characters, albeit with rather limited level ranges.
Eva Destruction AR/Fire/Munitions Blaster
Darkfire Avenger DM/SD/Body Scrapper
Arc ID#161629 Freaks, Geeks, and Men in Black
Arc ID#431270 Until the End of the World
Really? Weird considering that Desemondra isn't there, neither is Maelstrom....
Is this another bug? I remember that the rogues gallery was in the list of enemy groups when you were going to select a boss for your missions. Did the Devs remove it or is this a bug. PLEASE HELP ME!
