honestly enough i think this is the solution they need to go with, though i'd say to go one step further and add a rule that if you make an fc, all of your other characters on the server gets placed into it or are prevented from making/joining and removed from other fcs and the fc needs 10 or more unique characters (basically 10 different service accounts) before you can build an fc building, also adding a watered down version of airships/workshop for non fc houses probably would be nice. it would certainly help more people get a chance at housing in my opinion.
