Since the drop for one of my hunters, I have now found 2 more items for my paladin team. I found a bracer from a mythic+1 chest, and got a chestpiece from another emissary cache.
Still no legendary drop from any single boss on any difficulty. But lately I don't have time to farm any mythics or do daily heroics, I'm trying to do as many emissary world quests as possible on both my teams, and some easy mythic +1s.
