So considering the size of the servers....

they could have 100 wards and people would still get left out.

Actually at 100 wards, you might start to have lonely houses, because not every player is going to have time, gil, or desire to get a house. You don't need housing lot waiting for every green sprout. There should be a some level over-subscription for housing lots, so the housing lots have value, and housing lots do not go to waste.

And it took two weeks at least, for all the small lots to be sold out. Still all the medium and large lots are just sitting there open.
