Need help narrowing down my options: Too many alts

Ok, here are what I have right now all on the same server spread over 5 accounts.

70 Warlock- Soul Link/70 Druid- Feral Spec/66 Hunter/66 Druid/45 Paladin/45 Warlock

And my friend has a 45 Warlock, 45 Priest, 55 Warrior and a 66 Warrior.

Assume I am going to multi-box 4 and my friend will control 1.

Out of these combos, which ones would you recommend? I was thinking they control the warrior, then I can heal with a druid and dps with druid, lock and hunter.

Just looking for a little brainstorming for people who MB with a friend. Is it better for them to heal or tank?

As far as PvE or PvP content, assume 50-50.

Well, what does your friend want to play?

Tanking with a Warr would be an option, as this requires some action. So you would go for 3 DPS and 1 Healer - should be fine.

Or ... your friends plays the healer (Priest) with you playing a prot pala for tanking and 3 DPS. Fine too. Healing is more boring than tanking imho - if you can handle healing and DPS then probably the Warr would be more fun to play for your friend as he will always be in the "center of action".

I would go:

Warr -> Friend
3 x Locks for DPS and some CC and 1 Healer -> You

Either way will work... your friend can either heal OR tank. Really, they should do whatever you are not the best at :) If you did the healing, that would technically be a little less position dependant (meaning you wouldnt have to move much) so keep that in mind when choosing. I agree with the other poster... you should do 3 locks for your DPS (from what you have already) and maybe the pally as a healer (who can possibly tank in the future).
