Yo. So, here are my thoughts for a Resto build in 3.1. This is strictly a Main Tank healing build/Glyph setup. Let me know what you think. Any suggestions/comments you may have. I really do think with this set up, a shaman could effectively tank heal.
3.1 Tank Healing Build
*Edit* I took Healing Way over Elemental Weapons. Elemental Weapons is liek 45 more SP added on to Earthliving Weapon. While tank healing you'd be mixing in Healing Waves so I think it would be a more effective use of your points.
