Why is the shell FC in the US/Europe have anything to do with the JP servers?
Deleting undersized FC houses in the JP servers will not increase FC housing in the US/Europe servers.
There is a drastic lack of housing in the US/Europe because the FF14 share of the MMORPG market there just increased very rapidly and SE can't keep up.
You guys have a very large and competitive MMORPG market there.

So the point here is don't just ask an arbitrary question in the JP forum and use it as some proof.
