According to Paragon Wiki https://paragonwiki.com/wiki/Villain_Disruptor_Badge it says;
Any enemy from the following groups count: Rogues Gallery, Rogue Isles Villains.
Does not have to be of Archvillain rank to count.
Other good places to find groups of enemies that count include the Statesman Task Force, signature villains in Recluse's Victory, and Tip Missions.
Well, yesterday I defeated Flamebaux 4 times, Silent Blade 2 times, Hollow Point 2 times, Overdrive 3 times, and Desdemona 2 times and never got credit towards the badge count. My badge count before yesterday was 16 of 25 villains defeated. I know the badge in game says only villains from Safeguard Missions. So why don't the villains from Tip mission count like it says on the Paragon Wiki site?
