I was messing with the idea of the shaman group, something like pally / priest / shaman x3. Are you using round robin for the mana stream? I was thinking about that and I had an idea that may be helpful. Since I only have two accounts with BC upgrade I can't do this yet though, I'm alliance and can't Shaman it up without more upgrades to Burning Crusade. I was thinking instead of round robin you could just insert a null in the cast sequence to save keyboard real estate.

Something like this having them all bound to the same key allowing a rotating mana tide while keeping up a max number of Healing totems.
Sham1 /castsequence reset=combat Healing Stream Totem,,,,,Mana Tide Totem
Sham2 /castsequence reset=combat Healing Stream Totem,,,Mana Tide Totem,,,
Sham3 /castsequence reset=combat Healing Stream Totem,Mana Tide Totem,Healing Stream Totem,,,
Sham4 /castsequence reset=combat Mana Tide Totem,Healing Stream Totem,,,,,

So first press would get 3x heals & a mana tide, 2nd get's a replacement for the first mana tide with healing stream and drops the next guy's mana tide, 3rd press get's a replacement for the 2nd mana tide with healing stream again and makes the next shaman drop his mana tide totem and same for the 4th. If I have this set up right the next press would restart the order or just reset when you enter combat again. If someone knows about using the extra , to null a cast please let me know if this is correct. My thought is that above would cause the rotation with mana tide starting at 4, 3, 2, then 1.

I would think you could use the same concept for the various totem schools too, but my first ever shaman is only 28 so I'm just starting to learn about the various cooldowns and stacking abilities for totems. I know it would be nice to keep an earthbind down with though, and you could use null entry to keep just one of them dropping that while keeping Stoneskin and Strength of earth up.

Stoneskin,,,,,,,,,,,,,,,,,,,,,,
Strength of Earth,,,,,,,,,,,,,,,,,,,
Earthbind,Earthbind,Earthbind,Earthbind etc...

I would appreciate your input on how you worked out your totem farms and your thoughts.

=D Thanks for the welcome!
