Doesn't that mean that the prices for them were too low.

I'm not saying I'm particularly happy about how it turned out but that's how I see the situation, prices are too low and there aren't enough plots to go around. Hopefully doubling the wards in 2.4 helps a little but the demand will probably be higher still.

And seeing as there are people bummed out that they couldn't buy their house because they weren't awake when the servers went live the gil doesn't seem like a real issue.
