If they can put a stash after finishing a Horde. Why not a Blacksmith or Vendor to taking care of all the useless gears after opening chests? Those NPCs don’t have to be human ofc it can be a spirit just like from Trees of whispers.
It’s definitely more efficient for players in terms of quality of life than moving all gears to stash and bring it to town to salvage or sell all of them over and over.
I tell you once again Blizzard devs require more thinking.(I bet they can’t) or they must be so afraid of messing codes again if they try to bring a NPC in Horde.
