Here's my new "generic" pve 25 man raid totem rotation on my 5 shaman. Let me know if I missed anything useful.

/castsequence reset=8 strength of earth totem, poison cleansing totem, frost resistance totem, wrath of air totem
/castsequence reset=8 stoneskin totem, mana spring totem, totem of wrath, windfury totem
/castsequence reset=8 tremor totem, healing stream totem, totem of wrath, nature resistance totem
/castsequence reset=8 grounding totem, Fire Resistance Totem, totem of wrath, tremor totem
/castsequence reset=8 mana spring totem, tremor totem, flametongue totem, grounding totem

I made sure to leave out any totems that might cause aggro, like earthbind, searing totem etc... I'll throw those down as needed in a fight.
