Just give everyone a housing plot. By some miracle even Wildstar (rest in peace) managed to do that. Without melting their servers down. And even with furniture slot limits like 4000.

Wish SE would just scrap the ward system, 99% of all players don't even care about who lives in their ward. Wildstar had a great mechanic at the end where players could basically fuse their plots together in a own zone to create a neighborhood. No being forced to live next to a candy house. That would be so much better than the constant band aid fix of just adding more and more wards which will never satisfy the demand.
