Update Dec. 14: The Alchemy mount Vial of the Sands is no longer Bind-on-Pickup.
It would seem as though Blizzard did a stealth-buff with Archaeology today. After realms came back up from maintenance/restart, many reports are coming in that players are looting an average 3 to 6 Fragments per survey now (up from only 3)! I’m hunting down a blue poster to confirm the change but I have seen this in-game myself already. I’m looting anywhere from 3-6 fragments right now in the Eastern Kingdoms.
Will update this post as more news comes in…
