Questing with Mage/Priest combo...

So I chose a Mage/Priest combo, but I'm wondering how I should run with them. Should my Mage be my main and just Fireball all the time and my Priest Smite and heal when needed? I'm looking for any input from anyone that has done a Mage/Priest combo, what spells did you use and from 1-60, did you just cast Fireball and Smite all the time? I'm trying to figure out how best to utilize the 2 classes together.

BTW, I have a 35 Mage and a 20 Priest already. I soloed both of those, but playing them together at the same time, I can't do most of what I did to survive solo. Any tips on that?

I'd run your mage as your main, just personal preference really no explanation for it.

For your Priest you can use something like:

/cast [target=focustarget, harm] Smite, [target=focustarget, noharm] Heal

Setup your Mage as your focus for your Priest. If the mages target is harmable it'll smite, if its not harmable it'll heal it.

Also you could just healbot with your priest and AoE Grind with your Mage as Ice Spec.

I'd use the mage as the main also.

Mainly because; from playing a healer (in single mode) it can be a pain to get a heal off if the healer is getting hit. Too much inturuption.
