The housing system isn't perfect, which is something we can all agree on. However, let me just make it clear that FC's have every advantage over the individuals who are going for the house.

1. FC's require you to have four people. That's 3 more people that can potentially help the FC get a plot. Obviously 3 extra people isn't that much in the grand scheme of things, but it's still something. Now, let's just be generous/conservative and say that the average FC has 10-15 players who are active. That's 10-15 players that could help you get a house. Where are they?

2. If you have an FC, are people putting in their weight for the house? Or are they just on the bench swinging their legs yelling "WHERES MY HOUSE BABYRAGE?!". If you're a pretty substantial FC, you could collectively work together to just buy the plot off someone.

3. People rage about individuals getting houses but you do realize that that individual has to work twice or maybe thrice as hard as an FC does. They earn the gil on their own, they're stuck in queue just like everyone else, and it's them vs. x amount of FC members.

Mathematically, housing purchases favor the FCs. The only issue is that whoever's FC didn't get a house is mad because, well, they didn't get one. In the grand scheme of things, it worked out the way it was intended for other FCs.
