If SE just did this, and fleshed out the rest of the Ward list, it would at 3600 more houses to each world. I think that's more than enough right now for people who have been waiting for years until they add new residential areas. But truly, instanced is the way to go to ensure EVERYONE has a house.
I know I said it in
my post over here but it's actually kind of weird how the Ward list PERFECTLY fits 36 ward numbers, AND they made FC wards 1-18.
Meaning if there were 36 wards in total, the Personal wards would be the other 18. It's like, made me wonder if they are planning to add new wards, but didn't have time/weren't prepared to implement that before they realized more personal wards were needed urgently, which is when they readjusted to 1-10 being FC only. idk. I think they really goofed up.
