Spirit Healing - Build

Ive been trying out some builds and I wonder if this would work for party wide healing. It goes without saying that this build isnt meant to function without a dedicated single target healer.

Bloodsong/ SoS/ Pain/ Destruction/ Anguish/ Spirit's Gift/ Feast of Souls/ BoC

- Spawning power the highest and communing + channeling high

By not putting up too many spirits at the same time and spamming feast of souls, you have little downtime. No energy problems when combining Boon of Creation with SoS whenever you need mana, so always drain mana with other spirits before using SoS. Also these spirits can do some extra damage and serve as distraction from time to time. Downside is ofc enchantment removal and the lack of prot spells like most hybrid builds have.

Any thoughts?

EDIT: I just realised that spirits gift its range is very limited . Still doable, but dont think its actually worth it.
