I've gone with:
70 ToW Toon - http://talent.mmo-champion.com/?sham...00000000000000
80 ToW Toon - http://talent.mmo-champion.com/?sham...00000000000000

70 Others - http://talent.mmo-champion.com/?sham...00000000000000
80 Others - http://talent.mmo-champion.com/?sham...00000000000000

Personally, I cannot imagine not having LO. It's not as big, when Lighting/Chain Lighting aren't 90% of our spells anymore, but its still substantial.

If anyone has suggestions for my builds, I'd appreciate critique.
I'll be leveling five shammies, all five (elemental) will BG - but one will be my PvE raid toon and step out in arena for a healer friend.
