It even has a Mage specific section with some really insightful tips. It literally cut our leveling times in half on all of the characters we've used it on. You can read more about the guide here
Now, not only is the Mage one of the most rewarding and exciting classes to play at 80, it's also one of the best solo leveling classes and has the benefit of being able to level in a number of different ways - That mean's you can keep it interesting.
This Mage leveling guide will tell you all you need to know about mage's. From our opinions on AoE leveling and how to do it to more traditional fire/frost builds.
We usedthe Zygor 1-80 leveling guide to level our mage and recommend it to anyone who really hates leveling and wants it out of the way as quick as possible.
It's one of the most common questions and is a matter of opinion. Having tried AoE on our Mage we must say we prefer the traditional grinding and questing method. For those of you who are unfamiliar with AoE leveling it is grinding several different mobs at once using area of effect (AoE) spells. It can be done in 2 ways:
Frost - This method uses Blizzard. Getting improved blizzard is essential as this slows the mobs down.
Here is step by step guide, see below:
Round up the mobs, preferably on your mount.
When you have 7 or so melee enemies after you, Frost nova.
Run or blink away
Blizzard, then blizzard again, run back since they will be slowed and blizzard again if necessary.
Remember to throw in a cone of cold if your enemies get to close or you need some extra quick DPS to finish them off.
Generally speaking, though, we found that while the idea of AoE leveling seems incredible, in practice it's really not and is usually more trouble than it's worth. If you intend on grinding (AoE or not), rather than questing then be warned: Grinding is not the fastest way to 70. Questing is much faster, in particular if you make use of a guide to tell you exactly which quests to take and how to complete them in the quickest time possible.
While you can't handle as many mobs with fire you can take ranged mobs. If there's ranged mobs amongst them then be sure to kite the melee in tight circles close to the ranged as he won't chase you. We used that exact strategy to level from 43-48 in tanaris on the pirates and it was very effective (It's a very good spot, we highly recommend it).
