In short twice as much crying about housing...great. It will be a game of choose your pain. Place card click or let rng screw you over.YoshiP said there would be separate first come, first server and lottery wards. He didn't say wards would switch from first come, first serve to lottery after being filled.
Even the latter does little when it comes to house flipping. Flipping would continue to occur through the transfer of FCs. It's not like you need to be a member of a FC to do things with the members in that FC other than converse through FC chat. My FC has extended membership through our Discord. A lot of former members and just general game friends are effectively part of our FC without being in it.
There already are plenty of players who set up (or bought) shell FCs solely to get a house because it was the faster route for getting one when there were private purchase moratoriums on new wards or easier once the moratoriums were lifted but everything was sold. They're technically not abusing the system because they have just the one FC house allowed under the rules. They're just claiming what they're allowed as a FC because they were having difficulty getting it as a private player.
There are only two ways to kill house flipping:
Kill the wards and move to a purely instanced system that lets every player/FC buy the exact plot type they want. Clearly SE has no intention of doing that with the way they keep throwing effort and money at more wards even though nothing they are doing is solving any problems.
Kill FC housing and make all wards personal only through lottery purchase only. Doubt they're going to do that either because that means they'll have to come up with another system to give FCs a shared private space for their members to meet along with host the FC only features that currently require house ownership.
Oh wait, make that three ways:
Kill housing altogether. Can't flip what doesn't exist. That would be a disaster for them. It wouldn't kill the game since there is a sizeable chunk of the player base that cares nothing about housing but it would plant that seed of doubt in people's minds about what might be next to go.
