With the exception of hugs and kisses from our family, it seems nothing is free these days. The same can be said of World of Warcraft, as we noticed that their Tier 6 Shaman gear was a little... buggy. The tier 6 restoration set for shamans didn't actually have a price on it, making it essentially free. Needless to say, if you managed to "purchase" the tier 6 set that way, then you can kiss it goobye, as Blizzard is working on fixing the bug.

Drysc remarked on the forums about the "free armor", warning people about the potential problems they may have if they bought it:

We're aware that the Shaman Tier 6 restoration set currently does not have a cost requirement on it and we're working to resolve this as soon as possible.

We will be going to great lengths to remove the items already purchased, and tracking them down if they've been moved or converted in any way. Do not enchant or socket a gem into the items as they will be deleted when the item is.
