I always thought this was a pretty solid build:
chardev.org v6 ~ a World of Warcraft character planner Of course there are many different gear/spec choices at this level for an Elemental Shaman. I went into the Enhancement tree purely for instant Ghost Wolf. With my experiences as Elemental in the past, Ghost Wolf was always a big help. You could also go straight Elemental too for the extra crit / pushback reduction or spell range but personally I like having the extra escape tactic better. For proffesions I found that Engineering was a must, but aside from that Mining could be good for the health boost, Skinning for the crit boost or Herbalism for the extra HOT. Its all up to you and your play style. Some gear variations are:
Head: Miner's Hat of the Deep
Neck: Pulsating Crystalline Shard / Glowing Eye of Mordresh
Chest: Robe of the Magi - 150 Health
Wrist: Tracker's Wristguards of Nature's Wrath / of the Eagle
Hands: Shadowskin Gloves / Crimson Silk Gloves / Black Mageweave Gloves - 20 SP
Legs: Shadoweave Pants / Wolf Rider's Leggings of the Eagle - 32 armor
Feet: Wolf Rider's Boots of Nature's Wrath / of the Eagle - Surefooted
Ring: Lorekeeper's Ring
Trinket: Figurine - Jade Owl
Trinket: AGM
Trinket: Talisman of Arathor
