I am building up a 10box team and am thinking of using 5 shamans in it:

Tank1: Prot Paladin
Tank2: Prot Paladin
Heal1: Resto Shaman
Heal2: Resto Shaman
DPS1: Shadow Priest
DPS2: Frost Mage
DPS3: Destro Lock
DPS4: Ele Shaman
DPS5: Ele Shaman
DPS6: Ele Shaman

I don't like micro-managing toons, so I would prefer less active attention over more power, unless the set up prevents me from getting certain content done.

Pala Tanks1-2 are great, I tried DKs as well, needs much more attention.

I love Heal2-3 Resto Shamans, spamming chain heal is just carefree group healing and earth shield+riptide is automated tank healing. Add healing stream totem and I basically don't need to think about heals in my 5box. My priest seems to need more active attention to healing.

DPS1-3 should get most raid buffs, right?

DPS4-5 should do ok DPS

Am I missing something? Is this doable or requires the ICC10 content a different set up? Any reason from cata not to do that?

Would even a 10box with 8 shamans and 2 paladins have a chance? That idea I really find attractive
