*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*HORDE LEVELING GUIDE~*~*~*~*~*~*~*~*~*~*~

There is no “best” way to level. Certain people may prefer questing, some may prefer grinding. Some may prefer instancing, while others may prefer of combination of all of the aforementioned methods. Whether you prefer to level to 60 as fast as you can, or whether you prefer to take your time to enjoy every aspect of the game is entirely up to you, but this guide is meant to help you in your leveling process by providing you with the information you need to enhance your leveling experience.

Recently a new ebook released claiming to have the secret to making 60 gold an hour in World of Warcraft. I've had a number of people ask if this is possible, the answer? Absolutely. But you must have the skills and the knowledge of how to go about doing this. While the skills come with practice and time invested in game play, the knowledge can be bought and the "Cash Creating Guide for World of Warcraft" proves it.

Joana's guide was revamped 9/27/06 with his newest method for leveling from 1-60 in the shortest time possible! If you're never heard of Joana, he/she holds the record for leveling from 1-60 the fastest. No cheats, no exploits, just pure game play. He has a guide with walk throughs on EXACTLY how he does it and even includes a FRAPS video of the ENTIRE 4 days and 20 hours!
