Go back and read the blue post about the server locks. They also mentioned wanting to phase out mega realms entirely.
In the last paragraph he says “we believe the time has come to end the concept of a mega-realm”. So the locks aren’t just about the queues. They want to spread the population of the game more evenly. Personally, I don’t know that this is the best way to do this, but it’s what happens when you’re trying to play catch up.
