I think opening new wards will not be the solution.

The game has thousands, billions of players all over the world and they open only 200 or 300 houses? The problem wont end this way!

We, players who are online all the time , we see things in game, we know some ppl have many houses, even now they are selling the new ones 2x or 3x more expensive as they paid.
To start resolving the problem, each account should be limited to a single personal house and a single FC one.

As i said... Unless they put a house for every willing player to buy one, the problem will be on forever...

Some ppl, even show off, saying they have more than 1 house...
