Main Healing/Solo Healing as a Shaman

[Artega]

Now that I've been working on my Shaman, I've begun to plan him out for Lv.60, shooting for UBRS-level gear (and avoiding BG gear, since not all servers will have every BG active frequently, though mine does.) Additionally, I've planned out his talents, and wouldn't mind some feedback from someone who's already done what I'll be doing :)

The talent build is looking like this:

Enhancement, 21 points:

5/5 Ancestral Knowledge
5/5 Thundering Strikes
2/2 Improved Ghost Wolf
2/3 Improved Lightning Shield
1/1 Two-Handed Axes and Maces
5/5 Flurry
1/1 Parry

Restoration, 30 points:

5/5 Tidal Focus
5/5 Totemic Focus
4/5 Ancestral Healing
5/5 Improved Lesser Healing Wave
5/5 Tidal Mastery
1/1 Nature's Swiftness
5/5 Purification

The Enhancement talents give me a formidable melee presence, and the addition of Parry further increases my ability to be able to survive melee combat (especially important in PvP.) Restoration talents are focused on improving my healing capability; I decided to go with 4/5 Ancestral Healing, given that I drop totems frequently both in PvE and PvP (and they tend to get destroyed in PvP, not to mention that Fire Nova is a complete mana hog), and 5% Armor won't make a major difference in the long run. Purification is a 10% boost to the base heal values of my three healing spells, and seems like a natural choice for a healer build (versus getting Toughness and Improved Rockbiter Weapon out of Enhancement for an offtank build.)

The gear I've chosen for him is focused entirely on +healing, so it's not going to have as many stats or luxuries like +MP/time. Obviously, I'll probably sacrifice some +heal for those aforementioned luxuries as I see how the end-game goes for me.

Head: Insightful Hood (Cho'Rush the Observer, DM North)
Neck: Animated Chain Necklace (Ramstein the Gorger, Undead Stratholme)
Shoulder: Royal Cap Spaulders (Jandice Barov, Scholomance)
Chest: Vest of Elements (General Drakkisath, Upper Blackrock Spire)
Waist: Barrage Girdle (Cannon Master Willey, Scarlet Stratholme)
Legs: Silvermoon Leggings (Prince Tortheldin, DM West)
Feet: Merciful Greaves (Alzzin the Wildshaper, DM East)
Wrist: Loomguard Armbraces (Kirtonos the Herald, Scholomance)
Hands: Harmonious Gauntlets (King Gordok, DM North)
Finger1: Fordring's Seal (Fordring Quest Chain, EPL)
Finger2: Band of Rumination (Warchief Rend Blackhand, Upper Blackrock Spire)
Back: Hide of the Wild (Leatherworking)
Right Hand: Timeworn Mace (Prince Tortheldin, DM West)
Left Hand: Sacred Protector (Nathanos Quest Chain, EPL)

All the items combined with talents result with a +7% chance of spell crits (e.g. crit heals), and +316 Healing.

Using the math that I tried to remember from other posts involving +Healing effects and talents, I've come up with these heals:

Healing Wave X - 646 MP (3.0s Cast): Heals 2098-2351 (3.45 HP/MP)
Lesser Healing Wave VI - 361 MP (1.5s Cast): Heals 1020-1126 (5.94 HP/MP)
Chain Heal III - 385 MP (2.5s Cast): Heals 817/409/204-903/452/226 (2.23/1.12/0.56 HP/MP)

I used 2/3 (.6 repeating) for Chain Heal, since I couldn't remember the correct value offhand. I used 1/3 (.3 repeating) for LHW, and used the full value for Healing Wave. Both values were averaged and then divided by the spell's MP cost to generate HP per MP.

Assuming my math is correct, this clearly shows that - with Purification and an insane amount of +healing (for the gear level) - LHW is clearly superior to both Healing Wave and Chain Heal for most healing duties, though the huge healing amount of Healing Wave would still probably be preferable for healing tanks, due to their huge HP pools (as Treesh mentioned.)
