We tested this last night because the last time we did Gorefiend we did absolutely terrible, though I know that it seems to be random when this happens, I've seen warlocks come out of the fight with 12million damage from hellhounds alone with another warlock in the group somehow having 800k from their hellhounds, same gear too. Feels like there is probably a pathing issue with the demons as in the picture you can see our felguards just standing around too and the affi lock's fel hunter is hauling ass to the back as well.
Anyone happen to know a workaround for now?
