Just a suggestion.

After finding out where the Flagstone items come from (which is later submarine missions) I think it would have been nicer to see it be a craftable or an item obtained in the Firmament (more accessible to players in an understandable compacity).

I think something like a loft and stairs is more so an item that people would buy multiples of for use unlike something like a indoor moogle fountain which makes sense to make it a rare item as it is more so commonly used once. Not to mention these items will definelty be sold at high prices, understandably so, but the rng of getting them will also be an annoyance if you need it for multiple use or others in the FC are needing to use it as well. It\\'s also the first non wooden loft and stone stairs.

This as well as the fact that people that are not part of an fc or perhaps are in a fc that doesn\\'t have an fc house are not even able to get this item.

I just think it would nicer to perhaps get this item in other means that would not only get the players invested into something like crafting or utilizing an area/ mode more.
Just my thoughts on it ( I am part of an fc with a fc house fortunately but I just think of how it would be for players who do not have that accessibility let alone the fortune of getting an fc house ).
