I think if there are more wards, they should be dynamic per demand.

Balmung/Mateus: 5 more wards
ded World: 0 because there's 20 or so open plots
Medium World: 1-2 more wards due to threshold being breached but not as absurd

This would likely be a very stressful, intense undertaking. A solution I think is better is mixed housing. Instanced+Open. There's houses sprinkled in scenic locations so the cosmetics really stand out and if you want it, fight for it. But don't say you can't get a place because instanced is there. Because yes, video related is unacceptable.
