Edit: Please check out Shaman Raid build 2.0 for updates.
I have gone over the shaman trees over and over again. I have looked for synergies between each skill and tried to maximize the Resto build to be both viable for the normal raid healing chain heal casting Resto shaman and the crit happy proc shaman. All that work has now resulted in the following build.
The main concepts behind this build was maximize spell crit potential to increase the proc percentage of ancestral healing, improved water shield (augmented by improved shields in the enhancement tree) and ancestral awakening while still giving the shaman the standard healing talents for healing efficiency with mana and threat reduction.
One obvious omission from this build was the improved earth shield. The extra 2 charges stacked with the 10% healing on each charge would be nice, but I did not want to sacrifice any crit or threat reduction talents. I did think about dropping Tidal Force and Cleanse Spirit to give me the two points for improved earth shield, but I have found Cleanse Spirit too convenient to drop and Tidal Force would give me a much better chance to proc during tank healing.
Glyphs for this build should be as follows:
Glyph of Lesser Healing Wave (Major) – Your Lesser Healing Wave heals for 20% more if the target is also affected by your Earth Shield.
Glyph of Healing Wave (Major) – Your Healing Wave also heals you for 20% of the healing effect when you heal someone else.
Glyph of Earthliving Weapon (Major) – Increases the chance for your Earthliving weapon to trigger by 5%.
Glyph of Water Mastery (Major) - Increases the passive mana regeneration of your Water Shield spell by 30%.
Glyph of Water Shield (Minor) – Increases the number of charges on your Water Shield spell by 1
Glyph of Water Breathing (Minor) – Your Water Breathing spell no longer requires a reagent
Glyph of Renewed Life (Minor) – All stats increased by 5% for 1 min when you reincarnate.
To round out the proc shaman, the lesser healing wave glyph is a must for LHW spam for tank healing. As for the Healing Wave vs. Earthlinving it is a toss up based on your play style. If you find that you don’t cast HW that much then you might want to take the increases HoT proc, but having an ability that heals myself without having to think about it is a win in my book.
As for the minor glyphs it is always a toss up. I find the underwater breathing glyph to be very convenient and the extra 5% after a reincarnation could help fix a bad pull or boss fight. As for the water shield, it is probably negligible, but the less I have to cast it and waste a global cool down the better.
Keep in mind the build/glyph combo is not perfect and I am sure there are others viable versions out there. All my work on this build so far has been done in pieces while healing 5 mans and I won’t have the full workings of the build completely hammered out until raiding starts, but till then I will be confident that my experience and research have lead to a viable raid build.
