Most of us that are in end game raiding use the same 8/0/53 resto spec to negate as much AoE damage as possible, in the upcoming expansion with new talents such as Spirit Link, Ancestral Awakening, and Earthliving Weapon, new specs and ways to play (Less spamming 3 ranks of chain heal) will become viable.
Now that we've got confirmation that shaman WILL be getting new ranks of Chain Heal (Posted on the WotLK shaman beta forums by Koraa).

It's safe to begin making specs based on the assumption that we will primarily remain raid healers in the end game.
I sat down and took the old cookie cutter spec (8/0/53) and simply filled in talents where necessary on the resto side of it. Assuming that at least one, if not more dungeons will be set around frost type raid damage, Elemental Warding will remain worth the 8 points in the elemental tree.

Obviously very similar to the current raid spec.
Something that caught my eye in the enhancement tree was the Improved Shields talent which looks extremely beneficial to a resto shaman (15% more healing from ES and 15% more mana from WS) depending on whether this includes the passive Mp/5 and how effective Imp Water Shield is in the resto tree. Something like 0/8/63, incorporating both talents, might be able to do amazing things for shaman mana efficiency.

I'm very interested to hear what the shaman community has come up with on this. Here's hoping our talent trees don't get messed with too much
