Some thoughts.
Spirit Link: the more I think about this, the more I think this would push shaman towards pure CH casting in most all situations (provided it remains as is without a lengthy (>10 seconds) CD). As such, the talents devoted towards LHW and HW could be skipped. In single target healing instead of using HW you would simple keep SL up and CH, I'm guessing that even with the mana cost of SL it would still end up being more efficient than HW. Would need the specific cost/benefit of SL and the new max-rank CH to know for sure.
If you choose to omit the talents that focus on HW and LHW you can spend 54 in Resto and get most everything you'd like:
- Tier 1
5/5 Tidal Focus
- Tier 2
3/3 Ancestral Healing
5/5 Totemic Focus
- Tier 3
3/3 Healing Focus
1/1 Totemic Mastery
3/3 Healing Grace
- Tier 4
5/5 Restorative Totems
5/5 Tidal Mastery
- Tier 5
1/1 Nature's Swiftness
- Tier 6
5/5 Purification
- Tier 7
1/1 Mana Tide Totem
1/1 Cleanse Spirit
- Tier 8
2/2 Blessing of Eternals
2/2 Imp. Chain Heal
3/3 Nature's Blessing
- Tier 9
1/1 Earth Shield
2/2 Improved Earth Shield
- Tier 10
5/5 Tidal Waves
- Tier 11
1/1 Spirit Link
Key talents I'm omitting
- Improved Healing Wave
- Healing Way
- Ancestral Awakening
With 17 points left to spend you easily grab the 8 Tier 1 Enhancement talents, then probably pick up some of the omitted Resto talents. If you're assuming that you're not going to be casting much LHW or HW then Elemental doesn't hold much for you.
