Q: Have you done anything to limit the ability of higher level players to help 'rush' newbies through the game very quickly?
Blizzard: Players only get experience if they are close to the monster when it's killed. NOTE: There are several areas where you can't town-portal to unless you've completed the quests with 'unlock' them.
