Think on it like this...
You have billions of dollars to your name and could afford to have anything you wished. So you decide to buy a huge plot of what you believe to be beautiful land. Let's say... two hundred acres. Now you want an enormous house built on it for your family, and I mean ENORMOUS. So you hire a team of ten contractors each with their own team of construction workers. You throw your ideas at them as to what you want done and while half may say it can be done the other half may tell you it is impossible with the equipment they have. Now you have a conflict and the ground work isn't begun.
The trouble is what seems viable to you may not work largely as a whole. That is to say, what looks good on paper may not translate into 3D rendering. Whether that is real life construction or game code. What I am getting at is this: It is not that they don't read or are not receptive to ideas but they have to consider their limitations when considering the overall impact on the game. While I am sure they'd love to have a near infinite amount of housing wards, plots etc. think of how that would impact the function of the game as a whole. It worked in past games because rendering wasn't as strong as it is with more modern MMOs. Just like running a ton of background windows will cause lag within the game because of processing, over coding will cause servers to bog down.
