I recently got an e-mail from Blizzard asking me to come back. It is a "Scroll of Resurrection." Apparently, if you accept the offer you can get a handful of benefits. Quite interesting! One benefit is to get an alt up to 80. I was trying to level a Paladin as a Tank when I left WOW and I am somewhat interested in the proposition.
This also lead me to look at the videos for "Mists of Panderia." I was very unenthused when I heard about the new expansion. While it is very beautiful, it still strikes me as if the developers watched Kung Fu Panda one too many times.
