We need private instance housing
The supply of housing will continue to be a problem for players as there will never be enough supply to ever fit the needs of the whole server. Realistically, SE can't afford to meet demand if they continue to keep the housing system as it stands.
What we truly need is private instance housing to fix this problem.
This can give us potentially an 'unlimited' supply of housing, giving players access to the joys of housing (chococbo stables, furniture, gardening etc.). I understand it comes at the cost of not being able to interact with your neighbours, but it's definitely a cost I'm willing to pay if I can pay private instance housing at a much lower and afford price and gaining access to all the perks of housing realistically.
Simply just have a small private instance map and allow your wedded partner, party members and FC members etc. to have access to this private instance; allowing to share and show your friends your house.
And its really quite simple.
The saddest part is that houses are ALREADY instanced!!!
Whenever we access a house through the Glowing Entry Point we access a separate instance... The system is already build around an instanced house, but they just complicated everything with the housing ward deal. What really blows my mind is WHY SE don't just gets rid of the whole Ward deal which is only used to run around to the MB and the NPCs there (or leave it for players who want to live there, and open the option for non-ward housing).
Solution?
We already have the floating islands in Dravania, just give people a frigging house plot on a floating island and be done with it! SE wants to take GIL out of the economy, put a frigging price tag on the islands then.
How would it all work?
Place the silly caretakers and other housing related NPCs at any City-State next to the Aethernet Crystal. Cities are already player hubs, and there are MBs already in the same cities so players won't mind running to them.
When a player wants to go to a particular house they click on the Aethercrystal select an "Independant Houses" option and get asked for a 5 digit house address (and we already click numbers in the game at the cactpot deal so we know that can be done). That 5 digit combo yields for 99,999 individual houses (and no server has 99K+ players) so when you select an address you get whisked away into the house front yard, on a floating island where the house plot is.
And there, a self confined one-house plot on a floating island on its own isolated instance, surrounded by clouds and sky in a sphere of nothing. No neighbours, no houses next door to render, no nothing. Close the fence around the house so you can't walk/fly out and let people use the aethershard or /return function to leave.
Wanna build neighbourhoods? Give players the option to select a few neighboring houses and link their property to the others 5 digit addresses, so you can jump to the next house from their own front yard using those instance entry glowing orbs that SE loves so much.
Thats all there is to it. Move NPCs add a couple menus and create 3 floating islands of different sizes for the plots of the corresponding size. Is that so hard!? And don't tell me its so much data on it that it will stresses the servers or lag the game, its its own little instance, which will only be called from storage processed, exist on server memory and use bandwith while people are in it, once everybody leaves the place vanishes and does not consume resources other than storage disk space.
From there the houses will work exactly the same as they do now, you'll build, furnish and use the house in the same way, so no need to "overhaul" the whole system and piss players off, and no more "blame it on server stress" excuses. With less building cookie cutter wards that consume resources and go by unused and more separated spaces to satisfy player demand.
Simple and elegant, and far from imposible!
If I can come up with something like this I'm sure SE can come up with something even better.
SE just got to want it, and seems to me SE just doesn't want it.
