I really like frost in mages. I have never dual boxed 5 mages.. To be honest im quite the noob to it. But my opinion would be frost if you want to level quickly. If you went fire(Single mob targeting is the speciality there) Then yes. there would probobly be 2-3 wasted fireballs at least per mob. ... I made a quick little 10-60 fire spec for a mage(see below).... To be honest I see a lot of advantages if you were solo.. But in a group of 5 i would suggest frost... For frost you get the Ice Barrier which is great for survivability, and with Frostbite(15% chance to freeze the target with all chilling effects. 15x5= 75% to freeze target with every frostbolt round.) Frost warding(50% more armor with ice or frost armor. Awesome for survivability) Water elemental x 5. Winters chill, 1 frostbolt round and 10% more chance to crit on the target. Shatter, which means if you want to AoE grind you can quite easily. Considering blizzard could be specced to have a chilling effect and once again, every time blizzard hits it would have a 75% chance per target to freeze them again.. The more I talk the more I want 5 frost mages . Now solo leveling, I would have to say fire.. Penta leveling, all frost :thumbsup: .

Once again I am not nearly a pro at this kind of stuff. Chances are someone will find tons of flaws in my logic. If you do please do not flame me, simply give your reasons.

Heres the Frost 10-60 spec I made. http://www.wowhead.com/?talent=oZZAcbckfuhfdg0ox\
