Well I still prefer the Personal Apartment idea a bit more because despite the increase in wards SE will need to compensate for the addition of new players which will add new demand for housing. Then subtract the amount of players that are leaving the game as well.

If there is a growing number of the population when calculating population growth and decline (New players - leaving players) then there may never be enough produced for the Higher population servers.

Also the Personal Apartment idea is designed around a cheaper Personal Housing that would not completely replace Personal Housing since players that want a larger Personal Home will need to go for Personal Housing sicne Personal Apartment is designed to be smaller and more affordable.

Also, if players wanted to make their Personal Apartment larger they will have to pay extra for expansion upgrades but the upgrades will never go beyond the point to being better than Personal Small Housing and if they want a better Gardening they will need to buy a Personal Small House or better since Personal Apartments will only be able to support 2 seeds in the Apartment Farm Pot.
