Resto Druid 10m Heroic Feng Strategy

First of all, this fight is trivial compared to stone guardians and spiritbinder. Once again, not really a healer heavy fight. It's more of a dps check and tank not stupid fight.
Order we did the phases: Arcane Resonance phase, Shield phase, Epicenter phase, Draw Flame phase.
Glyphs: Lifebloom, Rejuvenation, Wild Growth
Spirit: I cleared this fight w/ 7.2k spirit. Didn't really go oom, but pretty close, as in can pretty much can only cast lifeblooms and nourish when we got the kill. So if you want to go higher or lower is up to you.
Talents: Oh.... Ursol's Vortex is a must this fight! I did this fight with Tree. I sorta just popped tree form whenever I felt like it, preferrably early as possible so can pop it more often. HotW was nice in the beginning, was pumping out 50k dps in the first 40 seconds of the fight.
Symbosis: Um, tank I guess? Doesn't really matter.
Healing strat: 3 healers. Druids aren't that bad for this fight.
So healing the 4 phase strategies:
Plant mushrooms in the center before pull.
Arcane Resonance: So we didn't hero this phase, since our dps could force the phase shift after 3 arcane velocities. The gist of it goes like this: see someone get hit w/ arcane resonance, everyone except the arcane resonanced person, stack on tank in mid. Explode mushrooms and heal the person outside, while the inside is damage nullified and spread before next arcane resonance hits. 2nd arcane velocity, no one needs to move (so have dpses derp like crazy), have your healers pop cooldowns, so Tranquility + devo aura is enough. Plant mushrooms in center again. Repeat w/ stacking for 3rd arcane velocity. Phase change!
Shield Phase: This phase is interchangable w/ epicenter phase imo, but our tank preferred this phase more because he didn't have a shield up for the 1st epicenter and our 2nd tank needed time before copying lightning fist. Um, so this phase, everyone must be stacked, and as soon as shield drops on the floor, raid moves away from it, even a little bit is enough. Place Ursol's Vortex down on the stack (I can preemptively guess where the stack is moving so can put it down while you run, but it's not that big of a deal). Dps should AoE these down while tank's shield is not up. Next one, stack doesn't move, derp like crazy, tank uses nullification shield. Repeat until phase change. This phase should be a mana rest period, save mana... use rejuvs and nourishes only.
Epicenter Phase: This phase mushroom the area where your raid is stacked (i.e. on tank). Stack on tank a few seconds before epicenter, and tank should nullify the damage, explode the mushroom for slow stackers. Then, if your copy tank isn't stupid, he'd stun the next epicenter. Repeat. This phase should be easy and mana regenning phase too.
Draw Flame Phase: Hero and burn! Well, this phase should only last 2 draw flames. Not much to watch out for, just everyone stack near tank still, run out to the sides (never behind) if you have the debuff. For the un-nullified draw flame, burn all healer cooldowns, Tranquility, devo, etc. And the boss should drop like a fly.

Cooldown: Tranquility is popped during 2nd arcane velocity in phase 1 and un-nullified draw flame phase. Innervate on cooldownish?
