The moment you can't pay your WoW bill its too late, imagine how fucked up you must be not to be able to pay $15 a month? Hell, Comcast is more expensive.
Perhaps "you lose your job and decide that your WoW bill is a non-essential expense, and make the one-time, non-trivial-to-reverse decision to cut it, which is much easier than every fifteen minutes crushing the urge to start playing."
