It's not change for the sake of change and the system isn't great when it punishes you for not knowing things that should be made clear to begin with. It's also not about being pressured into a bid, it's about letting us know the rules.
The economy, market, or whatever wouldn't be ruined by allowing new owners to back out of one deal during their whole time here, and it certainly would not ruin anything to at least put a warning somewhere.
I'm getting a kick out of the analogies though. One person compares it to a real life auction, another says it's not Monopoly. It's not like a real life auction because it's a game but it IS in fact like Monopoly because they're both games. What next? Comparing it to a fruitcake?
