Query: This offical strategy guide is great!!!

I have played World of Warcraft for two mouths now.This guide is a must to have!without it no one will know ,how to complete Quests properly.There are detailed maps ,professions,character classes etc...even detailed first day.For example :first day in Durotar.I would be totally losted without this guide.
