1) Its about the character, not the player or family. When I make a new character I have all the same restrictions as a character who was made by a new player.
2)I don't know what you are talking about, so please explain a little more on that.
3)There have been suggestions like that that I think were accepted but there is a list a mile long of to-do's and I don't think that is that high up the list.
4)Interacting with other nobles although its an issue with less players, as a new player likely won't start the interactions, they likely often need someone else to start interacting with them and they interact back, hopefully. Otherwise, I completely agree, the game needs more to do on the knight level, suggestions are welcome as I brought up the issue before and they didn't know what you would add and neither did I.
5)While there should be a limit still, perhaps increasing the amount of advies you can have by simply saying you can also have 2 for instance advies in addition to the limit of nobles active you can have. They are a grind that is good yet bad at the sametime for new players. Good because its gets them something to do, but they need to have a noble because thats where the social interaction and the core of the game is. (The core of the game being nobles/social interaction is with the nobles is the bad part of new players playing advies.)
