The ability to re-do old Instanced Battles

I, personally, would like to see the capability to do the instanced battles from the Main Scenario or Class/Job Quest again.

While the Class/Job Quest ones might be a bit weird, you would only really be able to do those as that class/job or else it'd end up kinda odd in instances where they tell you to use certain abilities to help deal with the fight, but all you'd have to do is just have a class-based lock for those battles and it should work out just fine.

As far as actually initiating/going into the instance battles, maybe make it in option at the cutscene viewer book from the Inn room? You'd be able to integrate it in the quest page, adding in a new number or maybe a different icon to signify that it's an instance battle, and be able to do the fights from there.

While it's not necessarily a big want of mine, it'd be really nice to see this be added into the game, as I, and a few of my friends, really enjoy the instanced battles.

Seconded! I've wanted to redo "The Return of Holyfist' forever!
