It's heating up outside, but the World of Warcraft is growing ever colder, as we get closer and closer to the Wrath of the Lich King expansion. And as usual, Joystiq's sister site WoW Insider is covering every temperature drop that goes down -- from interviews with world-first guilds to the latest rumors and updates on what we'll find in Northrend, WoW Insider is there. Here's our most popular posts from the last week in WoW.
