I am unable to see any reason to bring up system from dead mmorpg.
The games didn’t survive because of its housing system only shows housing system is a flavor to have but not a necessity.
Even Skyrim Online is still alive, it’s so called housing system got nothing to attract me to play the game.
Every game has their own signature feature and this Ward system is rightly FF14’s

If everyone is going to design a system same way, didn’t we also how that idea failed miserably.
Elden ring slapped, spitted, and stomped every single rpg maker’s face is the best proof.
