Square should totally take a look at this. Ragnarok is a big enough world with a lot of people for this "FCs" to own all the plots for themselves, while they only have 1-2 members in the FC and the owners doesn't even have enough level to own a house.
There are a lot of valid Free companies with small houses or not even a small house that would really enjoy the housing system and they can't cause of this egoist people.
