Just checked one of my old E-mail address today and had at first what I thought was a blizzard e-mail. It had said that the e-mail that I had listed on battle net had been changed to a new address. I opened up a new browser and went to battlenet from there and the my e-mail was still the same. Folks be careful their getting more clever.
Yeah, I've been getting some as well. "Problems with your mount" "Account is under investigation" etc.
Not really new. They've been sending out emails like this for a long time now. It still works on people who click first and check the link later.
