It all is a matter of who you are targeting with the game. The existing system is manageable, with minor confusion, for experienced players who have the initiative to learn the intricacies of the system. It seems as if it would be a nightmare to new players or lightweight players. If a lightweight player gets appointed to duke and wants to give one of his regions to a formal vassal that has an estate in another region may have to dig for answers to figure out why their pick is not on the list of potential appointees - if I understand the system right. The voting system makes it easy to get that position but can come with nasty surprises. It is possible to make all this more user friendly and accessible to the new guy or lightweight player. I am not really sure if I have really heard a good argument as to why it is preferable to no make things more user friendly.
