It's been a week since Mists of Pandaria came out. You've leveled your main to 90, decked them out in heroic gear, and enchanted all your stuff in preparation of raiding.

Wowhead's got a preview guide up on the new raid to answer any questions you might have, like "What attacks does this boss use?" or the more important "Does he drop anything for my spec?"
