Outside of garden sizes, and interior decorating capacity. Why would your FC "need" a large house? Are you a large group (50+)? FC centric features like workshop and personal rooms is the same regardless of housing size.

And I just checked lodestone and the FC of the character on your forum profile already has a large estate.

Yes we have a large FC we wanted to relocate. Change of atmosphere. We don't really like the current zones at all... but Shirogane is amazing.

Contrary to what you might think, reservations would still require a queue and you would be unable to make one when all plots have been reserved.

The idea for reservation was like this. Reserve a size... not a specific plot. Pay a fee. They open wards based on reservations. When the wards open give them 2-3 days to secure a plot (fee discount applied). If they don't claim then fee is forfeit and plot goes up for sale as usual.
