Team composition suggestion

Hello,

I have a question about team composition. First of all, I'm not new to dual-boxing and I have successfully dual-boxed several pairs before to 60 and had great fun in doing so (thanks to this forum :D)
Second of all, I can only afford two accounts and two computers, so no, triple-boxing is not an option, at least until my financial conditions improve =)

That being said, I want to level the following 4 classes on Alliance: Druid, Rogue, Shaman, Warrior. And my RAF expires in about a month + a week. I do have a main with lots of cash on that server, also Alliance, so gold is not really an issue.
My plan is to:
1. Level a pair from 1 to 60
2. Level another pair from 1 to 31
3. Gift one toon from 31 to 60
4. Solo-level the last toon (gasp, yes...) leisurely from 31 to 60 as a side hobby.

My guess is that,
1. For the first pair, I want Warrior + Shaman
2. For second pair, druid + rogue
3. Gift levels to druid
4. Level rogue slowly, since this seems to be the class that I enjoy the least.

How does this sound? Or do you have a better idea for team compositions?

Thanks

I would separate the Shaman and Druid, because they're both capable of ranged (caster) dps and heals as needed.
Play the warrior and rogue as the active toon, break follow on the ranged toon a short distance from where you engage.

Personally I would go Shaman + Rogue and Druid + Warrior, because the rogue will be a lot more fragile then the warrior, and earth shield can off-set this to a large degree.

Windfury + Strength of Earth totems, and support "pew pew pew" and your team will have massive dps for two toons.
Similarly, warrior (dps spec) with support dots/wrath will be good dps, I'd consider Dreamstate on the druid.

Thanks a lot for the reply.

Warriors ( Fury ) + Druid ( resto )
Rogue (what spec? haven't done my research yet, but does it really matter?) + Shaman ( resto ) only to level 30, and then gift 30 levels to Shaman?
