Union is power. Union allows to achieve harder things.
Things like attacking WoW's alliance HQ, Ironforge with a massive raid (more than one hundred of lvl 60 horde) and ending crashing up the server because of the endless guards+alliance vs. horde combats and the lag that was generated :)
Worth reading it. Even not having enough time to play WoW, it keeps looking actually like the best MMORPG available (if it just had housing...).
