Just compiling some random info for referencing.

Talents
Highest DPS currently - http://www.wowhead.com/?talent#hVhhqbZhbxfoxdIhusouVo
Another option is to remove Shamanistic Focus (Enhanc Tree) and Elemental Focus (Elemental Tree) and put 2/5 in Reverberation (Elemental Tree) or 1/5 in Reverberation (Elemental Tree) and 3/3 Improved Shields (Enhanc Tree)

Rotation (And ShockandAwe addon)
Huge priority for enhancement shamans to download the shockandawe addon from curse.com for rotation notifications.

The priority list for Enhancement Shaman

LS_0 - Cast Lightning Shield if there are no orbs left on you.

SW - Cast Feral Spirit if the ability is off CD. (Use your own judgement for timing with Bloodlust/Heroism)

SR - Cast Shamanistic Rage if the ability is off CD. (with 2p T10 should be used immediately)

SS_0 - Cast a Stormstrike if there are no charges left on the target.

MW5_LB - Cast a Lightning Bolt when you have 5 Maelstrom weapon stacks - Chain Lightning does less dmg against a single target as it doesn't scale as well. For multiple target fights then naturally using Chain Lightning will be higher dps.

FE - Cast your Fire Elemental if it is off CD (This will also free up GCDs for other abilities making it very useful during Bloodlust/Heroism).

MT_0 - Refresh your Magma Totem if it has expired.

FS - Cast a Flame Shock if there is no Flame Shock debuff on target.

ES - Cast an Earth shock whenever its off cooldown and the above are not available.

SS - Cast a Stormstrike whenever its off cooldown and MW hasn't got 5 stacks - this does a fair amount of damage but more importantly refreshes the SS debuff on the target giving 28% extra nature damage (20% base + 8% glyph).

LL - Cast a lava lash whenever its off cooldown and none of the above abilities are available.

FN - Cast Fire Nova regardless of single target or AOE targets.

MT - Refresh your Magma Totem if there are 2 secs or less left.

LS - Refresh your Lightning Shield if low number of orbs remaining (2 or less).

Totem refresh - if all else is on cooldown take the opportunity, if required, to refresh your totems.

Consumables
Flask - Flask of Endless Rage
Food Buff - Fish Feast preferred since we benefit from both AP and SP.

Weapons and Buffs
MH - Windfury Weapon
OH - Flametongue
-Always have Lightning Shield up (4-5% of average dmg)
-Both weapons should be slow (~2.6sec) for harder SS hits.
-FT is still greater than frostbrand because of lava lash and the amount of magical damage -done.

Hit Rating (Special Cap)
Raid (Assuming 3% Buff) - 368 Hit needed (446 without S.Priest or Moonkin)

Expertise Rating
Raid (Assuming talented into 9 exp) - 140 Expertise needed

Haste over Crit?
-Most of us see over 50% crit chance in raid buffs and it leads to haste being as beneficial if not more.

Major Glyphs
Glyph of Stormstrike
Glyph of Feral Spirits
Glyph of Windfury Weapon

Minor Glyphs
No priorities, usually nice to have Astral Recall though.

Gear Priority (Armor penetration Issue)
-Once hit capped arpen is slightly more valuable but it is still priority to get more haste and crit over arpen.

Enchants

Head - Arcanum of Torment (Ebon Blade rep)
Shoulder - Greater Inscription of the Axe (Sons of Hodir Rep) or the Inscription only Master's Inscription of the Axe
Cloak - Greater Speed (Swordguard Embroidery if Tailor)
Chest - Powerful Stats
Wrists - Greater Assault or expertise if you need it or Leatherworker fur
Gloves - Crusher or expertise/hit if you need it or Engineers Hyperspeed accelerator
Belt - make sure you have blacksmithing socket "Eternal Belt Buckle" and put a gem in it
Legs - Icescale Leg Armour or Leatherworking equivalent
Feet - Icewalker - or possibly Tuskar's Vitality or Cat's Swiftness for the extra speed boost
Rings (if enchanter) - Assault

Gems
Meta - Relentless Earthseige Diamond
Blue Slot - Nightmare Tear(+10stats), Enchanted Tear(+6stats), then Balanced Dreadstone (20ap 15stam)
Red Slot - Bright Cardinal Ruby (40ap) or Stark Ametrine (20ap or 10haste)
Yellow Slot - Quick King's Amber (20haste) or Stark Ametrine

-Always use a Belt Buckle for another gem spot, and do not waste a blue or prismatic in it's spot

nice post!
