I paid for month 2, but will I pay for month 3? I'm not sure yet. I'm starting to get a little burned out, but that'll happen when you play a lot like I have been... I think I may play til I get my main char up to level 60, then seriously consider a break. Temporary or permanent depends on if Blizzard ever gets the battlegrounds and raid content added and working...
From what I've read, your chars and account don't get deleted if you don't pay, so you can always come back after a few months and start playing again if you want.
