We really need dozens of threads saying the exact same thing? I'll just quote myself from another;

Make plots instanced, keep the zones as they are apart from that. Rather than one or two groups gathering at their nearest market board, you'd have a lot more people, since one plot could now have several peoples version instanced. Everyone would just walk to their plot, click on the gate and select which instanced version of that plot to enter, effectively the same as how we enter different wards/subdivisions/apartments now. Could have a system in place where a snapshot of players plots are randomly displayed in the zone to make it feel more lively, or just use template houses to fill the space... Either way, I think potentially being able to have unlimited availability of plots, higher furniture cap for gardens, and making the zones themselves more crowded are all massive benefits that I'd much rather see than "I can jump over the fence to leave my plot".

Heck, making the whole plot instanced might actually let you work some other seamless aspect in, namely letting us just walk into the house rather than selecting it and zoning in... Let that upper floor balcony door finally function, give us greater variety of furniture since outdoor and indoor furniture would now be the same thing, although placing a pond indoors does seem silly, but more freedom and options to create something is never a bad thing, IMO. Heck, could place stuff on the mansion balcony with such a system...
All SE needs to do is take the current plots, and move them to the instances, so if you're on say Plot 3 Ward 1, you're now first in the list of instanced houses on Plot 3, if you own Plot 3 on Ward 5, you're 5th (or 9th depending where you put subdivisions in that list). Everyone who currently owns a plot keeps it, by making it all instanced now the server strain is significantly reduced and additional versions of those plots can be created.
