On the EJ website. I thought I would bring it over. Several of these I did not know about.

Sunwell

Trash
Frost resistance totem: Sunblade Arch Mage casts frost nova
Purge: Renew on Sunblade Dawn Priest
Earth Shock: Holy nova of Sunblade Dawn Priest. You cannot interrupt the mindflay of the Sunblade Dusk Priest.

Brutallus Grounding totem doesn't work on burn in Brutallus ver. 4 on the PTR

Black Temple

Illidan: Phase 1: After each shadowfiend
debuff expires or the parasites die, water shield will proc. Use earth
shield during phase 2 for anti-pushback.

Phase 2: If healing one of the flame tanks, one of the few fights in
which you willl cast Healing Wave. Otherwise, use Chain Heal. Give
tanks Grace of Air and Fire Resistance.

Phase 4: Drop Earthbind near Illidan to slow the Shadow Demons.

Illidari Council: Have a shaman chain heal
the tank on Gathios (paladin). The heals should jump to melee DPS who
will take damage from his Consecration (2,250 damage every 3 seconds
for 21 seconds).

Earth Shock : Lady Malande's heals and her Divine Wrath. Don't
interrupt the Empowered Smite. It does far less damage than Divine
Wrath.

Reliquary of Souls (RoS): Phase 2: Essence of
Desire doubles your healing but eventually reduces your mana pool to
zero. Earth Shield casters to reduce spell pushback. At the end of
Phase 2, cast healing totem and earth shield on yourself, while you
still have the aura Essence of Desire so you have them for Phase 3. If
you run out of mana before the phase ends, [Totem of the Maelstrom] will allow a shaman to cast HW rank 1 for zero mana.

Gurtogg Bloodboil
Amplify Magic: Use on everyone. His DoT is physical.

Teron Gorefiend: Haste friendly. Fight becomes very healing intensive the last 45-60 seconds.

Supremus: Each time he shifts his gaze, it procs Water Shield.

Naj’entus: Haste friendly
Note: Dampen magic does NOT reduce damage done when the Tidal Shield bursts. Use Amplify Magic on everyone.

Trash (Karabor Sewers): Several mobs will require you to drop poison cleansing totem
Trash (Sanctuary of Shadow): Several mobs
will require you to drop poison cleansing totem, including Stalkers and
Primalists. Purge the Lightning Shield from Ashtongue Stormcallers.

Mount Hyjal

Archimonde: The boss has an aura or pulse
that will cause a charge of Water Shield to be consumed at the start of
the fight. This can result in the shaman temporarily getting aggro

Kaz'rogal: Shadow resist gear will help you resist the Mark of Kaz'rogal. It's a short fight that favors gear with +Int rather than mp5.

Azgalor: Shadow resist gear will help you resist his AoE silence.

Tempest Keep
Kael’Thas: Second add (Sanguinar) fears in both Phase 1 and Phase 3. You can interrupt Kael’s fireballs with Earth Shock.

Solarian: Earth Shock: Will not interrupt Arcane missiles. She will sometimes target totems for Arcane missiles so it can be worth dropping all four.

Void Reaver: Stand directly under the boss and spam chain heals on yourself and melee so you don't have to run from orbs.

Trash: Astromancer: The molten armor can be purged
Bloodwarder Squire: Earthshock will interrupt heals
Tempest Falconer: His fire shield can not be purged
Crystalcore Sentinel: His Overcharge (16,000+) can not be interrupted with Earthshock

Serpentshrine Cavern (SSC)

Lady Vashj Grounding totem absorbs Shock Burst. Absolutely crucial for this fight. Shock Burst stuns the main tank, causes him to lose aggro and does 8325-9675 damage. Used in Phases 1 and 3.

Nature Resist: Static Charges do 2,775 to 3,225 nature damage in Phase
1 and 3. Forked Lightening does 2,300-2,600 nature damage in Phase 2.
The poison clouds of the Spore Bats in phase 3 are also nature damage.

Earthbind: Slows Coilfang Striders

Tremor: Breaks the fears of the Coilfang Striders

Leotheras Fire Resitance Totem for whoever
tanks him in the Demon phase. Save Bloodlust/Heroism for when he hits
15%. If you drop a searing totem during the Whirlwind, a tank can stand
next to it since it will probably aggro Leo after the whirlwind is
over. Recall your totems prior to the Demon phase to avoid any issues
with the Searing Totem aggroing the boss.

Karathress
Earth Shock to interrupt heals Fathom-Guard Caribdis (Priest)
Grounding Totem will absorb the Frost Shocks from Fathom-Guard Tidalvess (Shaman)
One of the few fights where you should not use Amplify Magic.

Morogrim
Grace of Air: Give to tank
Amplify Magic: Put on the main tank. Up to 95% of Morogrim's damage is physical.

Hydross
Nature Resist/Frost Resist: You may need to keep one or both of these
down for the tanks, depending on available pally buffs and hunter
buffs. Searing Totem: Can cause wipes during the transition. Every
transition is a complete aggro wipe.
Dampen Magic: Use on tanks

Trash
Purge: Greyheart Tidecaller of Poison Shield
Purge: Greyheart Nether-Mage of Frost Destruction, Fire Destruction and Arcane Destruction (if mages don't spell steal it first)
Tremor: Vashj'ir Honor Guard

Zul'Aman (ZA)

Zul'Jin: In Phase 3 (Eagle form), pop your
trinkets and then drop Healing Stream. During this phase, using any
ability that costs mana (such as healing) causes you to take 1250
damage. However, you do not take damage from dropping totems. Your
Earth Elemental is immune to the damage from the tornadoes. Also have
any jewel crafters use [Dense Stone Statue].

Hex Lord Malacrass: Shadow resist gear helps.
Earth Shield either yourself for 100% protection against spell push
back or Earth Shield a DPS caster.
Amplify Magic on the whole group. Dampen magic will not reduce damage from Spirit Bolts.

Halazzi (Lynx): Grounding totem does not absorb anything.

Trash
Amani'shi Flame Caster: Purge their haste buff if a mage doesn't spell steal

Magtheridon
Earth Shock interrupts both the shadow volley and the dark mending (heal) of Hellfire Channelers
Stoneclaw: Will work on Burning Abyssals

Gruul
High King Maulgar: Grounding totem will absorb Kiggler’s (shaman’s) lightening bolt (3,000). Does not
absorb Krosh’s (mage’s) Greater Fireballs. Earth Shock interrupts the
heals of Blindeye (Priest). Use Tremor once Maulgar gets below 50%
health -- he fears.

Gruul
Amplify Magic: Use on entire raid, including the tanks.
Grace of Air: Give to tank

Trash
Tremor: Breaks Psychic Scream (fear) of Gronn-Priest
Earth Shock: Interrupts Heal of Gronn-Priest. They always cast this after they fear.
Purge: Removes renew on Gronn-Priest

Karazhan

Stoneclaw: Works on the skeletons
Earth Elemental: Works on the skeletons
Earthbind: Works on skeletons

Illhoof
Fire Elemental: Use to AOE the imps.
Earth Shield: Put on the warlock or mage who is AOEing the imps to reduce spell pushback.

Netherspite
Healing Stream: Drop at the end of the portal phase while you still have the +healing buff from the green beam.

Searing Totem: Aggro resets at the end of the banish phase. If a
Searing totem was down during the banish phase, Netherspite will attack
it and give your tank time to get control of the boss. A Searing Totem
can also be dropped before the banish phase and used to tank
Netherspite during the banish phase (assuming your raid does no DPS to
Netherspite while banished).

Aran
Grounding: Absorbs Aran’s Frostbolts (3500-3400), Fireball (3910-5290)
and Arcane Missiles (6300-7700 total) from Aran. Also absorbs water
bolts from the Elementals (1000-2000)
Earthshock: Interrupts Aran’s Frostbolts, Fireballs and Arcane Missiles. You can't interrupt his Pyroblast.

is destroyed. She does not target other totems (such as mana spring,
etc.)

Tremor: Breaks fear (Terrifying Howl)

Romulo and Julianne
Earth Shock: Interrupts her heal (Eternal Affection)
Earth Shock: Inerrupts her stun (powerful attraction). Best one to not interrupt
Earth Shock: Interrupts her holy damage (blinding passion ~6000)
Purge: Removes her Devoation (increased damage)

Remove Poison: Removes his Poisoned Thrust (which stacks)
Purge: Removes his Daring (increased damage)

Moroes
Poison Cleansing: Removes the Blind he casts on a target in melee
range. If you are an enhancement shaman and no one else in the raid can
remove poison, you MUST have this totem down since he could blind you.
Resto and Elemental shamans can stand further away to avoid being
blinded. Be quick to remove the poison from the tank because if the
off-tank is gouged, he will run rampant on your healers.

Purge: Will remove any buffs cast by the paladins on Moroes

Earthbind: Slows the adds

Earth Shock: Interrupts the Mana Burn of Baronesss Dorothea Millstipe (shadow priest).
