wow is fine, don't blame the game like the china's goverment and parent do.
you can play cheap offline game and still unable to make ends meet.
you can also success in life, cuddle and still get loot form lich king.

its all about a control on your daily life or time management, the balance.

even you sell your account, there some of us just buy a new account and start over.

find your priorities.
