Is there a way to actually use Plenary Indulgence?

Where can you use PI reliably? Savage mode raiding.

Ability is fantastic and needs zero changes. SE did a good job.

Please do not change PI, square enix.

there is one change they NEED to do though, and that is to (at least) double the buff duration. that is all it would take to make it actually useful in any content. please SE!
