Yep, OMGWTHZR is the new sound that will be ricocheting off the walls on Wednesday when everyone realises that Patch 5.0.3 has been loaded onto Blizzard's creaking servers and that all your talent points have been reset.
Go learn your new spell prios, rotations, GLYPHS, TALENT BUILD and get ready to update all your addons come Wednesday.
Be prepared!
thats probably why we are having trouble with connecting....their "creaky servers" are dying
