Since so much of your leveling and money making will be done through NPCs or “mobs” Blizzard has developed a very powerful questing system. Not only is it powerful, but the system allows for less tedium in your monster killing. Instead of killing the same monsters over and over again, the quests will allow you to have some variation in your leveling activities. Along with the very slick quest system there will be swift transport between zones. From boats and zeppelins to swift moving animals, you'll get to where you're going.
