The idea behind PoM is great, it's the ability that needs adjusting. SS every 300 seconds just for 10 seconds? FEELS like this was meant as a hardcore CD, a CD that can be used in a rotation when Divine Seal is up perhaps. Heck, it's the same timer as Benediction, of all things. That's the MMO'er in me, telling me something went overlooked in this ability.

I think lowering the timer (obviously) and adding something else to it is long past overdue. Maybe make it a random chance to increase Det, Crit OR SS? Or even better, have it be a smart ability and let it choose the highest of those 3.
