Was stated recently that since most servers have available housing, they feel it's fine the way it is. Hurts the servers that don't have availability, but they are all linked so adding more housing to the full ones would add more empty housing to the ones with availability, eating up more server resources. Personally, they should make the housing separate per server. That way if Balmung needs 20 wards but another lower pop server only needs 5, they could do just that. As it stands now, if one server has 10 wards, they all do, regardless of availability, which sucks.
