I'm surprised that it took Blizzard a full year to implement this. I believe that I play WoW too much, and I'm what would be considered a relatively light player. For instance, I still don't have a level 60 character, and yet there are many many thousands of players who have not one but several level 60 characters. I love the game, but if you truly have that much time to play, you're probably playing too much, or you're forgoing other responsibilities (e.g. schoolwork, job, etc.) to play. I know it sounds like blasphemy, but it's probably more true than many are willing to admit.

Blizzard has given parents some tools to help them limit how much time their children play the game. Per account, parents can log into the World of Warcraft site, navigate to the account settings section and activate the parental controls features. They're given the ability to set which times their children can play the game. It's all locked behind a parental control password that's different from the WoW login password.
