This is important to fans who have a Shaman and recently or soon own a Tier 6. The item will be deleted and you might lose whatever you spent on the gems. Read the alert:
Drysc: “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.”
