Why are housing so expensive. For a game feature it seems very prohibitive. I could understand when there were only companies who could afford housing. Now there are many who can buy them for personal use. Everyone should have their own house now in the city they wish to add it. If you want a bigger house then make people pay for it.
Instead of making housing such a niche enterprise, why not add it as a selling point to the game. Even Wow will be giving all players housing in the next expansion.
