It's very interesting to me that Magtheridon-EU's transfers are specifically for the Horde. That's not something you see very often. It's also interesting that they're trying to get the Horde off of the server rather than trying to coax more Alliance on board. I suppose the Horde is just that dominant on the server that the overpopulation is specifically because of that faction, and losing more Alliance would be a disaster. It's home to Ensidia, which is a Horde guild, so I wouldn't be shocked if that attracted a lot of Horde attention to that realm (and drove away Alliance in return). Will this help that? Maybe!
A few of the destination realms have been destination realms before, too. Haomarush, Xavius, Ahn'Qiraj, and Burning Blade were all up for transfers a few months ago. Will it work out this time? Maybe. We'll see, won't we?
Well, whatever happens, good luck on your new realms to all who will be hopping on board the transfer train!
