main a mage, and keep your priest hidden in the group, STOP USING THAT AOE.. my god lol. if you ahve a rogue on you, bnlink away, frostnova, but NEVER stand there and let him stab you. you are not a shaman, you do not have a shield and you do not wear mail.

you shouldn't be using fireball unless you are 41y away from someone, it is easily avoided by every class up close and you should be focusing on spreading your guys out and spamming scorch and fireblast. I dont box mages, but I used to play one, I almost never used fireball unless the target was sheeped (which you should use) or really far away.
