Personally, I hope the new forms are a subtle hint at a Blizzard reversal in its reluctance to add in some class-specific content again. While doing something cool for every class is a daunting process and the required resources are extensive, it's been shown that players react favorably to that type of content. In the meantime, check out the epic cat forms for worgen, night elves, tauren, and trolls over at Wowhead.
It's open warfare between Alliance and Horde in Mists of Pandaria, World of Warcraft's next expansion. Jump into five new levels with new talents and class mechanics, try the new monk class, and create a pandaren character to ally with either Horde or Alliance. Look for expansion basics in our Mists FAQ, or dig into our spring press event coverage for more details!
