I just thought it would be cool to have some sort of challenge set up by/via Shantotto where we could visit remade (mechanically) iconic battles from XI. Like others have suggested, have her pull us into a zone that resembled sea to see how we would fair against XI's AV, or Tu'Lia against Kirin. Have her create the BF using her magic so it simply resembles the place of the fight, we don't actually have to be teleported to Sea. Rewards can be iconic gear from XI, or just tomestones, not too worried about that. I thought Yoshi said he wanted this to be a very fan service-esque entry into the FF library, thus the suggestion for XI to be next.

I know a lot of people are tired of hearing comparisons and there is this hatred for the numeral XI, but I'm not asking to change XIV at all. I'm asking we make a CT w/an FFXI theme, instead of FFIII, that's it. The best part is since it's instanced if you hate XI that much, you never have to lay an eye on it.
