World of Warcraft developers recently sat down and held a Twitter Q and A with fans with some sweet results. The dev team at Blizzard tried to keep the focus mainly on Cataclysm class, talent, and Mastery systems designs. Yet, the devs covered everything from questions about the updated talent tree, to ideas surrounding new glyphs, new pets, defended arguments against certain PvE and PvP encounters using the new skill sets and much more.
This only scratches the surface, however. There were dozens of questions the devs took and answered if not a few hundred. They really put some effort into this one.
