Razorgore the untamed...

...I received this morning an email from Blizzard Customer Service, which says that my guild (The New Dawn - Ragnaros EU server) was the first killing Razorgore the Untamed using the original Blizzard designer tactic.

In effect we used a kinda unusual tactic to down the damned Razorgore... but I'd like to know if this mail is true or is some fake (if it's some fake I think I'll begin a check with a good antivirus :))

Anyone can help (maybe a blue confirming this? ^_^)
