Unbalanced Game

I'm really disappointed with SE for not seperate the housing residential between the private and free company. People of my FC already gather all the gil for a long time to buy a shirogane large house but when we trying to buy a plot in shirogane, the first thing that happened, server congested.. next, the residential area already was bought for private purposes.. Many of the FC member already hate this game since SE not taking seriously about the problem.. we paid the game, we paid for the expansion and the content.. why the residential area are still limited? PLEASE TAKE INTO CONSIDERATION FOR WHAT HAPPENING NOW..
