[Moonkin x3 + Shaman x2] vs [Moonkin x5]

Toons available on my accounts:

1) 80 druid, 74 warrior, 62 priest
2) 80 druid
3) 80 druid
4) 63 shaman
5) 63 pally

I'm thinking that since I'm leveling my shaman and pally, I might as well bring three others along with the trip to 80. I can easily use RAF to get two level 60s on (2) and (3) which would leave my priest on (1) to join the leveling group. However, I'm having trouble deciding what two additional toons I should level.

I could make it two more moonkin so that at 80, after transferring to different accounts, I'd have 5x boomkin. The benefits would be that I could set it up with one being a tank druid and do stealth runs. Also, 5x typhoon should effectively wipe out any graveyard rezzers in BGs. The cons are that as long as I am running 5 druids fear still hurts me... bad.

I could make it two more shamans and then run either [3x shaman 2x boomkin] or [2x shaman 3x boomkin]. The benefits would be that if I level up two more shaman then I would have another 5 man team to PvE with (pally, 3x ele shaman, priest). I could also run around in BGs with shaman/moonkin mixtures where I'd be protected with totems, but lose the shock effect of 5 druids springing out of stealth.

Any suggestions?

I am in the process of building a druid team. I also have a shaman team, and they are quite similar, but their complexities are completely different. I would go with 2 more druids. Druids are more flexible, as they can tank heal and dps, whereas shaman can just heal and dps. IMO the only downside of 5x moonkin is having to go out of moonkin form to heal. I was going to macro in a sequence of HoTs from the 4 alt boomkin, something like /castsequence [target=focus] regrowth, rejuvenation, moonkin form or something like that, i guess i need to throw in a reset too. Then I'd need some sort of aoe healing macro, same macro, but targeting themselves. My main team has a dedicated priest healer and I just target the tanks target's target, or AoE. I am so used to the holy trinity setup, I am tempted to run bear tree and 3 owls, and use a similar macro strategy. But all this theorycrafting pales in comparison to a video I saw of someones 5 69 druids running an instance, and just murdering everything and using CC to make it ezmode. Only on a few bad pulls did he even need to heal... And even in balance spec, you still have bear form if a boss requires it.

I did end up going with the 5x boomkin team. Currently I'm leveling up 2x boomkin, pally tank, and shaman healer. When they reach 80 I will transfer the two new boomkins to different accouts so I can have 5x owl goodness. I haven't decided how I'm going to gear up the two boomkins who are on the shaman and pally accounts, but I'll likely just dual spec one druid to a tank and another to a healer and then just roll with an all druid PvE team. I haven't regretted the decision yet and am actually trying to stay away from shamans as much as possible... I definitely think shamans are the strongest PvE class, but I have a feeling that some totem nerfing is going to come (non stackable effects) and I like my treants too much to give up.
