I think there's something wrong with this feat because I spent over 20 minutes killing these dreggs and none of them counted I was still stuck at 360 out of 450 could someone please look into it
I had this same issue, then I realized I was killing dreggs in Halls of Power II content instead of Halls of Power I content, and those dreggs in HoP II didn't count. Try that, if that doesn't work out, take it to the issue tracker.
I know this sounds like a stupid question but which content is that again? lol I've been killing them in New Genesis where the big dreggs are that you can either teleport or kill
Yep, just looked up which feat you meant. Its Dregg Or Alive, and those have to be killed in the instances I listed.
