Nope you didn't add enough plots SE...

People like having ward communities. I know I do. I don't wanna see them go away.

Nothing says they have to go away. The current wards could be retained for those who like the wards, are willing to compete for plots and can accept the risk of demolition.

Instanced house plots would be for those who want more than an apartment/FC room and don't really care whether a neighbor can see their house.

Right now if you picked up my personal house and stuck it in an instance with a mock backdrop displaying a fake ward, I wouldn't know the difference. I see maybe one or two other players a month in the ward at most. Things are busier around our FC house but then we're a moderately active FC and member friends stop by fairly often. Instanced housing wouldn't prevent that from continuing to happen. MB convenience wouldn't even have to be lost with instanced housing if a ward layout was used for a common area with just the house plots being instanced.
