One thing that I recently ran into that I didn't see mentioned was phishing emails. I have been recieved emails for over a month now stating that my account is under investigation and that I'm trying to sell my WoW account. I was almost certain that they were phishing emails, but with MoP right around the corner I decided to submit a ticket on just to be sure. The response I got was what I expected, they were in fact phishing emails, and one thing that I thought was worth sharing was the customer support rep stated that any email I get that is actually from blizzard will be from one of the following, or The phishing emails will have a return address very similar to one of those just listed, or one that sounds right but isn't. Just thought I'd share this for people that may have not been through an expansion release before or anybody that may be curious.
