Constructive criticism is great. It often leads to some out of the box ideas that really help. They may not get used verbatim, but they help.
Unfortunately, a lot of the ideas you have come up with will lead to situations that we have already seen won't work. Dwilight was a lot like the situation that would have evolved from your 3 nobles per region idea. The situation that you hoped would develop, never happened. Dwilight was widely regarded as the most boring island in the entire game. It wasn't until the realms expanded enough to actually come into contact with each other, and the free land disappeared, that the island really started picking up.
The game had gone through a lot of changes overt the years. We've tried a lot of different things. Although a suggestion may seem new to you, we may have tried it before. At least some version of it. It's not that we're ignoring your suggestions, but we've spent a lot of time discussing things, and formulating a plan. We've considered a lot of the stuff people are suggesting. You just haven't seen the discussions.
