Assuming I'm not healing, I usually start out with Malo AA and Slow AA or Counterbias. In groups I find dots to be pretty much not worth casting due to things dying so fast. If you are playing a melee dps you can cast the puma line, but if you don't have a melee dps it isn't worth it. Also pet attack. My experience has been that shamans aren't worth boxing unless you are going to heal, since their dps is very lackluster.
When I duo'd with my Nec / Shm: AA Malo AA Slow (counterbias usually on named) (sometimes cripple, not sure if it really did anything useful but for awhile it was there) Pet Attack (pet relocate sometimes) quick dot 1 quick dot 2 poison dd
Spells with a refresh timer. Aside from usual shaman slowing/debuffing/healing duties, one macro: Poison nuke Short duration dot Short duration dot Canni Might have had an ice nuke in there, or slam, it was a while ago and i was only 95. Shaman easily outdamaged the warrior with raid equipment. Switch up the order as circumstances dictate.
Best Dps results is like this: Spell AA Spell AA Spell First Spell is quick poison nuke so you can cast it again
