Funny you should mention the Korea situation. So at least on Balmung when they launched housing one of the first things people asked, "How will this work when they merge servers?" Guess what it turns out the paid professionals didn't ask themselves that question. From the reports it sounded like they asked the Korean company to hold off till they could make the server population irrelevant, like they have done for us.
It is also why they are so dependent on cross server and instance content. They don't have an answer for server merges that doesn't make them look like complete (word of choice here). You could be on the shittiest population server and still be able to get everything done with enough cross server tools.
Does anyone ask why they have limited resources they don't put harder restrictions on purchasing. Sure we would all complain if owning a house required you to do "Payroll IV" or "Bring your A game" or "In the outfield VII". They have numbers on what people are accomplishing it would be easy for them to balance the amount of players who actually get a house.
Actually this is considered a violation and a report able offense. You do know that? Inflated price so someone will move is not a currently endorsed move by the talking heads.
