House raffles get suggested every day, though people usually call it a lottery. They're a terrible idea.

The main trouble with this: You can win a house while offline.
So botters can log to one account, enter raffle, log to another, enter raffle, and keep going. You could enter a raffle with 8 FCs on the same account, giving yourself 8x the chance to win as any random first-time-personal seeker.

The current system makes sure you're at least running the client if you're going to win a house, and only lets you attempt on one character per account at a time. This suggestion looks to be a small quality of life upgrade on the surface, but after spending 10 seconds to actually think it through, it offers an obvious and massive advantage to exploiters and this would greatly reduce house availability to players.
