So I was just thinking of an idea and was wondering how you guys would feel about it.
All FC's get a little plot of land and a tiny lame house for free just for getting Rank 6 and getting Allied with a GC (I mean come on we save the world and are allied with your nation the least you can do is give us a house).
To upgrade said house it cost oodles upon oodles of gil and has certain requirements such as clear X dungeon or whatever, don't really care what just something.
That way big FC's can still get their mansions but at the very least everyone has SOMETHING.
Feel free to expand on this idea/change it.
