Today marks the official end of the Burning Crusades. You're forced to respec, play with the new UI, and view all the changes in the world around you which you have grown to know so well. It's a very somber and bittersweet day, yet exciting at the same time. So while you wait about 4 hours for your patch to download, you have a good bit to reflect on.
In closing, all I have to say is... Arthas, bring it on... I'm ready for all Northeren will be dishing out to me.
