As of yesterday afternoon and lasting through January 28th at 2:00 PM PST, a number of free realm transfers have opened up in the US in an attempt to repair some harsh population imbalance. Bornakk does warn, however, that if they fulfill the transfer quota before January 28th, they will end transfers early so they don't end up in the exact same situation on opposite ends. If any of the below transfer offers suit your fancy, get it done before it's too late.
What's interesting is that in a few of these instances, they're only extended the offer to Horde players. These servers include Illidan, Mal'Ganis, and Warsong. Considering Mal'Ganis is home to the infamous Goon Squad, this isn't the most surprising thing in the world. Interesting, yes. Surprising? Not in the slightest.
