1) Example: City defense (Besieged from FFXI):
-Defend a city against an invading army. Repel them from reaching their goal and defeat their bosses within an hour to route their attack.

How this could work in the story: Perhaps defend against Imperials skirmishing against Eorzean patrols.

They could perhaps maybe do this with a time travel expansion kind of how they did with FFXI with Wings of the Goddess for the crystal war.
