Most shamans should know about totem twisting, Its where you place one totem down, like Windfury, and then replace it with another totem to get both buffs at the same time.
This works great in 5 mans if you are a caster but you have more melee in your group and dont want to sacrifice your Wrath of air totem
Just make a macro that does
/castsequence reset=5, Windfury totem, Wrath of air totem
Just push this button once for windfury totem and then again for Wrath of air totem, Your party now has windfury for 9 seconds and you have your 101 spell dmg and healing. Just repeat this every 9 seconds for a nice DPS boost.
It does take some paying attention and I find it works best with healing spec'd shamans since there is enough time in their casting to take the time needed to put down both totems.
You can also replace it with Grace of air totem for the 2nd one if you are an enhancement shaman or dont need the healing and spell damage as much.
