I don't know if everyone missed this on the front page but Blizzard has added a new item for Archaeology in the most recent PTR patch:
Mantid Artifact Sonic Locator
Requires The Lorewalkers - Exalted
"While this item is on your person, any new digsites you discover in Pandaria will be of Mantid origin."
The item stacks to 20 so it sounds like it will be consumable, but still this is a way to guarantee the next dig site you find will be one that you want (if you want a Mantid digsite).
What are your thoughts on this? Is it a good direction for Archaeology? Are you waiting with bated breath for them to add similar items for every other archaeology race?
Personally I think it's a fantastic idea (especially if they are single use items, it'd be a bit powerful otherwise)
