Disciple of Varashta Sacred Rituals wording clarification

Disciple of Varashta's Sacred Rituals ascendancy wording states:
"60% of your current energy shield is added to your Armour for determining your Physical Damage Reduction from Armour"

The way one may understand it, it adds Armour. It doesn't.
The stat is:
current_energy_shield_%_as_physical_damage_reduction

Meaning, it does not actually grant Armour and it doesn't scale with armour% modifiers, it only grants Physical Damage Reduction % based off your current Energy Shield%.

As such, I suggest rewording it to clarify its actual mechanic:

"60% of your current Energy Shield is used to determine your Physical Damage Reduction, as though it were Armour."

Thanks!
