Ok so for most of MOP I have been using this exploit and figured I'd post it here as it still worked after 6.0.2. Currently any bags/boxes you have in your inventory before a patch are reset regardless of what you took out before it. I farmed about 40 big bags of linen before 6.0.2 and only left bandages in them and they all resat and have had unclaimed black market containers in my bags for over a year and the loot has changed with each patch landing me the pureblood firehawk. I haven't seen anything about this posted here but if it has been feel free to remove this. Besides that start farming bags like the ones from the townlonge steppes rares and just leave 1 junk item in each, buy lockboxes and remove just the gold etc.
