Pros and Cons of going back to WoW?

It's a fun game with a lot of stuff to do and many places to explore. bad part is that you get fat and some people obsess over the game and you have to have almost no life to achieve stuff in like raids and other dungeons. I play the game off and on, but my ex who is one of those no lifers all he does is play that game and rarely goes out. basically, play the game in moderation. :P
