Talent Specs
Elemental/Resto - The Electric Healer. (40/0/21)
This is a build used for 5v5 and seems to be generally accepted Elemental build.
Restoration (0/7/54)
In general there are 2 version of Resto-Shaman-specs. Some Shamans prefer to put 8 points in Elemental-tree to get "Elemental Warding", but most put 7 points in Enhancement tree to get 5% mana and to reduce the cooldown of Grounding Totem (very important against caster dps teams).
Restoration (0/9/52)
Resto Spec that takes Improved Ghost Wolf as I use it often enough that its 2 points well spent. And when I don't have it I wish I did. May or may not fit your play style.
