I am 4 boxing a priest/3x mage team and was just interested in how people who have leveled mages did it. I am not sure if I want to stay frost or go fire. Currently at 69/68 and have been leveling frost on my mages. I like it for it's mana efficiency. Just wondering if people preferred to go fire for full on firepower or if they also enjoyed the mana efficiency of frost. My team leveled as arcane up until 63. At that point running around and grabbing a ton of mobs and mowing them down with 3x Arcane Explosions and 1x holy nova was good enough to destroy lots of packs..

In these later levels thats not really a good option in terms of mana usage and alot of mobs have a ton more HP than they did at those earlier levels. What do you guys think? Stick with a frost spec or go with fire.
