Same here, my wife plays Wow I have no interest in it. What I love about GW2 is that I dont feel like I am pissing money away not playing it.
Pretty much why I'm hesitant to take out subs on any MMO at the moment. If they started selling subscriptions per hour, I'd sub to quite a few games again. Like, say a 120 hour timecard that counts down only while you're logged into the game.
