My guild killed Kil'jaeden heroic tonight and our raid leader forgot to set master loot so we were using personal loot. We killed the boss and not a single person got gear or even gold from personal loot (a couple bonus rolled gear).
Did this happen to many people ? I heard it also happened to a popular WOW Twitch streamer (Quin69) group and they were using master loot so it seems like there is probably an issue with the boss.
