This is indicative of how humans relate to each other, more than how people play WoW. Your friend has obviously connected with the people she plays with in WoW on a deep level. That's not a slight on internet relationships, or a commentary on modern online society - it's just an observation on your particular friend's interactions. There is nothing inherently wrong with that. And just because she isn't earning millions doing so doesn't mean she isn't an awesome person. I think, if anything, those people who have such devotion to a social group - regardless of that social group's reason for existing - are particularly noble.
