If you are like many people leveling an alt, or starting fresh, you are probably looking for the fastest WoW leveling guide. There are many great guides out there, in fact I would be hard pressed to talk bad about any of them. What you need to do is sit down and determine your needs, and what you are willing to give up for the fastest WoW leveling guide. 

Each guide has its own strengths and weaknesses. If you sit down and evaluate the guides you can easily find out which is good for what, and needs work in other areas. A couple of the guides are really only good for a couple of classes. Others only rely on free programs for any form of in-game functionality. Simply knowing what you need in the guide will go a long way to helping you here. 

A big concern with many people at this stage is price. Many of these guides start out around fifty bucks. This may seem like a bit of money, but I can tell you that it is a good price. But this is a decision that you have to make, I cannot make it for you.

I will tell you that I have used a couple of the free guides myself. They were fairly well written, and did me well, but having used the paid methods I can say that I will never go back. The key feature that you get with many of the paid guides is an in game add on that will practically hold your hand while you level so there is no confusion. The guides are often written in text, so you can print them out, but is often it is not needed.
