Triple mage dps 10000%. The more mages you have the more damage each individual mage will do in both fire and frost. Fire mages can stack ignites together and overall have higher dps but frost mages have frostbite (15% chance on frost damage to freeze target for 4 seconds) and shatter (50% crit against frozen targets). I was leaning towards triple frost mage because 50% crit sounds amazing, but you can’t freeze bosses; and on trash you can just spam arcane explosion to do crazy aoe damage.

Im going to be running prot pally+ Resto druid that will go straight for imp thorns + triple fire mage for dungeon farming. Mages will have two points in arcane subtlety for 40% reduced arcane threat so with ret aura, thorns, consecration and the 40% decreased threat from arcane and the 30% reduced threat from salvation my mages will never pull agro while aoeing. I will also melt bosses by just spamming fireball and stacking ignite. At higher levels I’ll use a /cast at player macro with flamestrike to get the dot from it up before spamming arcane explosion.
