3 boxing ideas

I've made a couple of 3 box teams since Raf upgrades and was looking for some advice.

My first team is 3 dwarf priests, and my main question is if it would be a good idea to add a warlock and remove one of the priests (i can only 3 box, my comp won't allow more, and in primetime i can't do 3)

I'm thinking that the warlock can provide me with a tank, healthstones, a soulstone and add to the shadow damage. Also i'm not sure how well the priests stack. Would 2 locks and a priest be a better idea? I'd have 2 times the soulstones, 2 tanks or 1 tank and a utility or dps pet. I want to keep at least 1 priest, as i think the shadow spec talents are just to much fun, and i've never had a priest high enough to use them. Also I'll be leveling on a pvp server, so I'll be getting ganked, and probably alot.

My next question is about a 3 mage crew I'm running, I have 3 female gnome mages (my daughter is 7, and she helped me design them and they are named after her). Mainly I'm wondering whats the best spec to level them as. I was thinking of starting out fire, to just burn shit down as fast as possible. At what level should i consider switching to frost for added survivability? I'll be leveling them on a pve server so I don't need to worry about being ganked.

I want at least one more 3some, and was thinking I want a horde 3some, just haven't figured out what server or what classes. I'm pretty much limited to shaman, hunters or druids if i want to go all ranged. 3 druids might be able to do instances, if ones feral, ones resto and ones boomkin. 3 shaman would need a tank at a minimum to do instances, and hunters could probably do some if the mobs are all green. Which of these trios do you think is more viable? How hard is it to play different classes when the spells don't exactly mesh the way a single classes would?

*BUMP*

I too am looking for 3 box combo...

was thinking 2x mage and pally... or 3x druids...

can anyone throw some imput/ideas our way?

its so fast to level with RAF, I'd just roll 3x priests, 3x mages 3x locks, etc and mix n match later. You will learn each class inside and out if you are only running one. Then you have a ton of levels to "gift" so you can instantly make a pally tank, warrior tank, druid tank, etc. :)
