This build's an interesting variant. I'd like to say I invented it, but I didn't. I stole the idea from some random person Varda PUG-ed with when he subsequently pinged me the build and then I tweaked it.
Context: This build is amazing in two scenarios:
1. In a team that already has very heavy prot ability coming off another player. That basically means (a) ER ele, (b) ST rit, or (c) tons of midline damage mitigation (SY!, TntF, EB, Panic, etc.). This build provides the complementary redbarup.
2. Normal mode, where its heal/sec simply outpaces the monsters' damage/sec by a huge margin.
Outside of those two situations, the total lack of damage mitigation and almost-total lack of spot healing make it pretty undesirable. (Don't say I didn't warn you about that.)
Build:
16 Resto, 13 Spawning
RitLord
Recuperation
Rejuvenation
Life
Recovery
Spirit Light/MBS
Signet of Creation
Summon Spirits
Usage:
1. Maintain spirits at all times. (Except recovery if not facing conditions at the moment.) Use RitLord every time you cast a spirit. Use Summon Spirits to avoid needing to recast.
2. Use Summon Spirits to keep Rejuv w/in earshot of people taking damage.
3. Use Life as if it were Heal Party. (Because of the faster recharge from RitLord, casting Life will cause the old Life to die, resulting in a party heal of at least 90.)
4. Use Spirit Light/MBS for a spot heal if needed.
The combined effect of Recuperation+Rejuvenation+Life is that your entire party is under the equivalent of a permanent ~14.5 pips of health regen. Assuming that (1) monster damage is not exceeding 29DPS (after mitigation) and (2) your party's mitigation is good enough to avoid people getting spiked out, all red bars will head towards full without terribly much input from you.
Once you get the hang of it, you'll find yourself spending a lot of time wanding things because the build is so automatic.
Enjoy.

) or maybe even Preservation when it has to be all about passive healing?
