There were a lot of beta changes over the weekend. More blacksmith craftable weapons and armours have been released; Lake Wintergrasp (PvP zone) was made available; Mages, Warriors, Rogues, Shaman, Druids, and Warlocks all had their talents updated; Naxxramas tokens can be used to purchase a healer shield and a tank shield; many new class glyphs for the inscription profession have been released.
I still yearn for a laptop to hook myself back into playing, grarghhh. :o
