Netherweave has jumped right to the top of listings in the Auction House, while Arcade Dust makes a nice showing at 7th. Of the Primal elements, only Earth is on the first page (most likely because it's the most farmed from all those Earth Elementals in Nagrand). It also comes from Mining, so it makes a good showing on the Most Gathered Items as well-- Copper leads that category by double everything else, though, most likely because of all the jewelcrafting going on. In fact, while Soul Shards are still number one, Copper Bars are the second Most Created Items in the realms, too. Interesting that you have to go to page 3 before you see a jewelcrafting item, though-- two sets of battleground tokens (Arathi Basin and WSG) are being made more than any Delicate Copper Wire.
Warlock pets remain on the top of the Most Dangerous NPC list, but King Bangalash and those nasty Defias Pillagers have company-- apparently people are back playing their mains, and raid bosses like Shade of Aran, Gruul, Nightbane, and the Maiden are killing players by the thousands. The Most Complete Quests screen has interesting info, too-- almost all of the quests are newbie Blood Elf quests (there is at least one Draenei newbie quest mixed in, but BEs have the clear majority). You'd think people would be completing quests in Outland to level, but three months after BC release, maybe that's not the case anymore. According to the stats, it seems like the large majority of players has gotten their mains to 70, are raiding Kara and Gruul, and leveling up their Blood Elf mains.
