What's your point, exactly? I'm clearly talking about the exterior plots here, which are not instanced... If they were instanced, SE could hopefully get around the ridiculous server limitations they currently impose and as such offer people far more plots than is currently possible...
As far as I know, right now every plot in every ward is constantly taking up server resources, whether anyone is in those zones or not, because they're not instanced. Interiors and apartments on the other hand, the server doesn't need to load them if nobody is using the instance, so it saves space and doesn't load them, thus allows us to; 1) have far more of them, and 2) place far more furniture in them. Apply that to the plots themselves and end this ridiculous scarcity that only exists because of woefully poor planning on the developers part.
Seriously, there is no point in plots being the way they are. Literally nothing is done with this concept. Housing wards themselves are dead, people basically only sit in their own plot/the nearest market board. I'm sure some enjoy walking around the wards, heck I do sometimes, but it really doesn't justify the ridiculous limitations it imposes on the housing system... Can even keep that concept in part by just locking off the plots and making them instanced, you could still walk around Lavender Beds, you'd just need to zone into a plot rather than seamlessly walking into someones garden. I really don't think that feature is worth also saying "Only X number of people can own a mansion" because we're limited on how many can be added as a result of it...
Heck, instanced plots would arguably make the wards feel more alive. Rather than one person occupying plot 1, you'd have multiple people occupying the instances there... The market boards outside would feel much more lively as a result, since you'd be drawing a greater number of players there. More socializing. More people talking about their houses. Better than the few groups hovering around the market boards we currently get...
