My girlfriend doesn't play WoW. However she probably knows more about it than most people. She's been there when I hoot and holler over vent when I've defeated hard bosses like Kale'thas. And she's listened to me whine and complain about how I think everyone on the internet hates me (I'm kidding of course, it's only Retribution Paladins and Death Knights who hate me, or maybe it was Protection Warriors and Elemental Shamans, I can never remember).
Occasionally she can be found browsing the site to see what I've been working on. Like the time that I was in LA at BlizzCon and Mike Schramm sent me forth to risk my life in a fire. That went over well.
But despite my immersion in the game and the community surrounding it she has yet to pick up a sword and fight the Horde.
I'm trying to figure out if that's something that should change.
