If you listened to our podcast on Saturday (which was heard on the new 24-hour WoW Radio), you heard us chatting about taming the Ghost Wolf, a neat little trick that Hunters (like our own Matthew Rossi's wife) have discovered to let them tame a very rare, very special pet. I personally made my opinion known on the show: that this was a great little reward for level 70 players willing to put the time and effort in to get the pet, and that Blizzard should definitely leave this as is, intended or not.
And now, the great Mania points us to this forum post by EU Blue Issuntril, who confirms that even though the taming wasn't actually intended, Blizzard doesn't have plans to address the issue-- Ghost Wolves are here to stay.
Great news for Hunters willing to go the extra mile for a cool pet (and for Hunters who have already done so-- would definitely be lame to log in after all of that work and find your spectral pet missing). Kudos to Blizz for letting the Ghost Wolves run free.
