Is there someway to add a relationship bonus fo close relatives, such as mother/father and full Siblings.
It is annoying that your younger brother will always launch a rebellion. I'd much rather it was half brothers, cousins and uncles who took up arms as a pretender than your closest family. Unless they have some real issues for some other reason I do not think that they should rebel that easily and instead help you out.
Maybe add some events that removes this relationship bonus if you are unfriendly to your close family (dont grant them marriage/help them to become landed etc).
