The Spirit Realm

Why do foci and healing AAs not work with Mantle of the Wyrmguard ? They do work however with Redeemer's Breastplate .

I think typically spell duration AA and focus works with clickies, but any AA or focus to increase direct healing (and nukes too) does not. You cannot crit a clicky heal for example.

This is also true for shamans. (e.g. Turgur's slow from TA vs heal from Mark of the Brood Warden).
