They need to remove the FC perks from FC housing except for buffs and obviously the social aspects of why FC's are created to begin with. Airships and gardening should be available for all and not simply for the FC leadership for which is the case in most cases. Some of us use FC's to share a house with alts as well and personally that's a very legitimate reason for creating a small FC at the moment given SE has found that sharing a house with alts is something they have a hard time doing.
They need to make it so only one character per server can be the leader of a FC just like only one personal house can be purchased per account per server.
