Eh.... I was probably a bit to obtuse with that attempted snarky response, but the main point I was indirectly getting at was that the concept of PvP with housing, while emergent behavior, is probably not what SE had intended, and thus, a flaw in the system.
In an ideal world, SE would be able to get the supply high enough that it would drop demand for housing so the entire concept of housing PvP would disappear.... yet that isn't happenning.
And here's something that may not have been made clear... if we have one person enter 8 raffles, they would need enough gil to cover 8 houses as each raffle ticket is the full purchase price of the house. For some that's trivial, but as soon as they win one of those houses (assuming that they do), they automatically get refunded the other 7 (assuming those raffles are still running that is). So while what you're talking about would be doable under this system, it's going to take a pretty hefty amount of gil.
The main thing I'm trying to explore is how a could work with the intent of letting people get away from the house so they're not camping it for like 16 or 17 hours - which is a very concerning thing that the current system is encouraging.
