I'm fairly sure this is something that has been discussed before but I have not seen any threads about it so i figured I would post it here. The other day I DE some LFR loot and I didn't receive any haunting spirits like I did a few weeks ago, I was wondering if it was just bad luck or if they hot fixed it so I thought maybe if I use Blizzard item restoration on Battle.net and DE the items again I might get the Haunting spirits I was looking for. I did the restoration for the LFR loot and for some 496 gear I had disenchanted a week or so ago. When I received the items in my in-game mailbox I was surprised to find that I still had the same number of blood spirits in my bags as I had before I did the restoration and that blizz had only taken back the sha crystals from the previous disenchants. I DE the items again and I netted 5 free blood spirits but sadly no haunting spirits (I'm assuming they hot fixed it). I also got 1 extra sha crystal from a x2 proc.
steps:
1) DE some 522 gear
2) Go to blizzards item restoration page
3) restore the items you DE
4) profit
