I could get behind this!

In another game I fiddle around with (Defiance)...once you complete a story arc, the game gives you the option of replaying it (though I don't recall if there are rewards or not, offhand). It would be awesome if we could do the same here with the main story quests (at least) to give us something else to do when leveling up alt classes/jobs other than the aforementioned fates/dungeons/leves.
