When boredom sets in, I turn to the Spirits.

As you can plainly see, I'm bored. So I will regale you all with yet another WoW raid guide, this time for the Shaman!
First, pick your Race. For Alliance it shouldn't be too hard to decide on a race...seeing as only one exists that can play a Shaman, Draenei. For the Horde side, I'd still go with Orcs because of their Blood Fury racial to give a bonus to Attack Power or Spell Power.
Next, the heart of the subject, the placing of Talent Points. There are 2 possibilities to choose from Enhancement (melee), or Elemental (caster). Elemental is very nice, but in my opinion for the more end-game raids, Enhancement pulls ahead.
For Elemental it's obvious what you'll be using as far as equipment, but for Enhancement, using 2 slow one-handed weapons is the way to go. Obviously, seeing as the staple of your damage, Stormstrike, causes weapon damage from both weapons, so why wouldn't you dual-wield?
Now for ability rotations.
Elemental- (While having Flametongue Weapon on your weapon) Flame Shock, Lightning Bolts until your Flame Shock DoT is almsot out, then Lava Burst.
Enhancement- (while having Windfury Weapon on the Main Hand, and Flametongue Weapon on the Off-Hand) Stormstrike, Earth Shock, Flame Shock, Lava Lash.

Here are the Talent Builds I designed for the Shaman Raid dps in you.

Enjoy. Remember, don't make me get the Tuna.
