Spirit Visage buff idea

it current passive is, Unique: Increases effectiveness of all sources of health restoration by 30% (including health regeneration, life steal and spell vamp).

My buff idea is what if it included shields as well, 30% self shield, 10% incoming shield, 10% outgoing shield, 10% outgoing heal?

This would help non naturally healing tanks for vs ap team , and sups vs ap team.
