, btw. Also, not politically correct or safe for Tumblrites.
On a serious note, you're going to out level the content long before you complete the zones. If you're just trying to level, you'll be best served by clearing out 2-3 levels of quests and moving on to the next zone. If you're going for completionism, I found the zones rather entertaining and probably worth doing the full questlines for if you've never seen them..
