Not sure if this has been reported but it has been present in the game this entire time. Bug is simple. Some specials/elites are not popping up in the kill feed when killed, my character still says a voice line to confirm the kill. From what I can see its nothing to do with the gear you kill them with, I could huse the same weapon on a group of 4 ragers and only 1 could pop up so I dont know whats causing it. It is happening a lot though. somewhere between 20-40% of specials or elites are not showing up in the feed when killed.
