I’ve pickpocketed over 70 npcs in the past 2-3 hours – all of which have a chance to have a box as loot, but I’ve gotten one junkbox.
I haven’t seen a junkbox since I came back. Well, not off BFA mobs. I assumed they took them out of the game like everything else.
Nazjatar has junk boxes but yeah you are better off farming junk boxes in MoP. They nerfed the MoP ones a while back, but the MoP ones are still better than the Nazjatar ones if you know what you are doing.
Aww crap. I meant to post on the classic forums. Seems the drop rates for boxes and quest items was nerfed.
