An @Blizzard.com return address is the appropriate address, Oobi, but most of these phishing e-mails spoof the return address in order to look legitimate.
Luckily you did not submit any account information, I'd recommend checking you system for possible keyloggers. Odds are you didn't pick up anything but you can never be too careful.
** Computer Security Recommendations ** http://forums.worldofwarcraft.com/thread.html?topicId=1778038509&sid=1 Just based on that link and that the e-mail claimed that you "will be suspended or have your account closed" I can say with certainty that it was fake. We do not threaten with a suspension or closure, if we believe your account violated our Terms of Use we take action based on the violation and it is up to you to contact us.
Some fake/phishing e-mail examples can be found in the link below as well as many examples, please check it out.
