Whichever spec you choose has a major impact on your playstyle — perhaps more than any other class due to mage’s heavy reliance on their spellbook. Arcane mages will be casting Arcane Blast and Arcane Missiles; fire mages will be using Pyroblast and Fireball; and frost mages will be using Frostbolt and their Water Elemental. Each of these specs has their benefits and all can be used by a leveling mage — though anyone with a fondness for kiting will particularly appreciate frost’s abilities to freeze and slow enemies. But in short: pick a specialization that seems interesting to you and go for it.
Most classes we’ve talked about can fill several different roles in combat, with talent specializations focused on different roles. Wow Power leveling Mages, who can only fill the role of DPS, have three talent specializations that tweak the way they dish out hurt on their targets. Here are your specialization options, as described by Blizzard:
Arcane: Manipulate the arcane, destroying enemies with overwhelming power.
Fire: Ignite enemies with balls of fire and combustive flames.
Frost: Freezes enemies in their tracks and shatters them with Frost magic.
