Happened to me last night after I started playing my newly geared barbarian.
He was paragon 6 at the time, around 60 MF from gear/follower and had 2 NV coming in to this pack. Never had this happen before despite having so many many hundreds of runs with maxed MF on my other 70+ and 50+ paragons. Oh well.
The gloves were tasker and theo if anyone cares, gloves always suck :P
Oh yes, and on the previous run I found innas pants with 170 dex from a goblin. That was my first green from a goblin having found only legends from them before. One lucky barb.
