What a pointless discussion, not even answering the question.

Royal Authority is a filler, you use it when Goring is up and you are ok in aggro(assuming you're the active tank).

The most common physical rotation for PLD is Goring-RA-RA-Goring. Which can be replaced easily by Goring-Rage-Rage-Goring if you feel you need an aggro boost, which is rarely the case
