I don't see any issue with the changes at all. Buying a random small just because you could take advantage of a loop hole to skip the queue into a "better" small or a bigger plot always felt like an unintended process. And it's not that you can't relocate, you just don't get any special privelege for wanting to do so.

The only issue I see with the system is that they're still not allowing alts to be registered as part owners (or some form of special guest) in a house that you do own.
