Here are some great guides for power leveling:

Brian Kopp's World of Warcraft 1-70 Alliance Guide  eBook, $35 *****

Finally, the only 1-70 Alliance Guide that is written by a professional Gamer. This is just like Joana/Mancow's Horde Guide except for the Alliance. He listed every coordinate on everything and linked all quests. This guide will allow you to get an alliance character from 1-60 in under 5 days to 7 days /played time solo and from 60-70 in 3-5 days. Brian has a starting guide for Night Elves, Humans, Gnomes/Dwarf, and Draenei so any race/class can use this guide. There are no exploits or cheats in this guide. It seems like you need cheats to level that fast but you don't!

Joana's World of Warcraft 1-70 Horde Guide  eBook, $37 *****

JoanasWorld.com is here! It's about time ain't it? Joana made this guide for people who are tired of grinding levels, looking up how to do quests and trying to figure out the right ways to level up. If you're confused as where you should be leveling at, then you have come to the right place.

This guide contains the same leveling strategies, questing patterns, techniques, and secrets Joana has used to get the best record time to level 60 on a new server, which is 4 days 20 hours /played! The realm this was achieved on was the Jubei'Thos server, and Joana is now currently getting prepared to set records for 1-70!
