That is more like LoU (Lords of Ultima - EA Games) which is now; the servers are no longer online(May 12, 2014). I concur with your suggestion and also see incoming and out going attacks would be great also along with support for the whole alliance... If all these suggestions where implemented they would get thousands more players that have been looking for a similar game as LoU... I know LoU had a strong loyal following for several years... but EA shut the servers down for newer games.... and nothings out there really close to the game.
We can only hope that they add module that would implement similar game play.
