WHY???

Why does City of Heroes do this to me?? I manage to wean myself slightly of the addiction, and thus enable myself to spend more time in World of Warcraft, and then they go an announce the next free content update to the game and make me panic that I'll never get a villain to 50 before it launches so I can be one of the 2000 people per server that makes a newbie Blood Widow when it goes live. :p
