This looks like it will help them to deal with population issues without having to shut down or consolidate realms, at least for a while. That always seemed to be a sign that a game was "in decline." It won't help high population realms that have a severe faction imbalance. I think Stormrage US and Darkspear US are both in that situation. It will be interesting to see if people take them up on any free transfer offers if there is less concern that they'll be moving to a ghost town or just going from one lopsided server to another.
