I think a part of the issue is I don't this this game's design has a place for it. I think if you wanted a once-use super ability that is per player and not an LB, then I think a different principle would be needed instead of once per hour. It might fit somewhere like Eureka, which is kinda based on the same kinda endgame as FFXI.

Not sure what the right way around it would be. I guess 1 per dungeon/trial/raid? Use it wisely or wompwomp, you missed out. Then maybe 1hr refresh on the field or in Eureka and Bozja (when we get it)
