I did for years after one of my deployments had me hooked on it when playing it at a deployed contractors home. I played from near the end of Vanilla all the way until Deathwing, and after a small break came back to try out MoP. The game is incredibly fun with friends, but it will easily turn into a job if you let it. It's also frustrating trying to get everyone on the same timeline to raid and even more frustrating when people take smoke breaks between every pull.
