Ive quit wow twice. First time was during TBC and sold my account for 500 bucks. Then I got the itch a few months later and rolled a new account and played till a few months into WotLK until I got bored again because shit was just re-hashed instances and repetitive. Don't plan on coming back even though I get a small itch every now and then because there are no other MMOs out there that interest me more than a few months.
