It's not as simple as "Just go buy a house." There is decent competition on Large/Medium plots across most wards on our server, most of them with 8+ bids even in goblet. (This doesn't sound like much if you're on an older server, but for us thats a notable increase.) With the announcement of Xbox integration, and 7.0's player boom heading to Dynamis people have had their eyes on our housing for awhile now, and have had time to accquire many juicy plots for resale. The last thing we want is for the housing problems to be amplified and made even worse on Dynamis, and the solution to solve these problems isn't exactly clear cut, but a little GM moderation, or investigation of certain Discord servers would ice a lot of the illicit house sales.
It's certainly commendable to try opening the GM's eyes to this, we can only hope for them to do just a little bit of investigation into it.
