Dual classes opinion on pairs

[Ghlave]

I've got 3 sets of guys I'm getting ready to push now that I've got my new account caught up with my alts. Originally, I was going to level up a warlock duo, and two sets of mage/priest combos. I know mage/priest does very well, but I'm considering instead of leveling them up as such, to level them as pure class combos (mage/mage, priest/priest, warlock/warlock).

Any thought on the best combination between the six toons I'm working with?

Well, for dual box, I'd like to use mage/mage combo, SPriest+warlock combo. 2xmage's damage is great, as for Shadow priest and warlock, the dots will make trash die much faster.
But why not use triple box? it's awesome for prist+mage+warlock combo, you can have free water/food, portal, resu, tank(pet), and various buffs.
Obviously you need another new account

Triple boxing is tempting, but right now I'm in it more for the long haul of using RAF to get some alts of mine up. Priest/Warlock could be nice, I may have to re-adjust my thinking for that.

My main is a Holy pally, and i've currently been 2boxing her and a boomkin. Shockadin build with the extra bonuses that a boomkin brings ? heals = mana, more crit, buffs, etc. it's a bit of a deviation from the norm, but It's pretty devastating.
