Patrons had the incentive to help their vassals to keep them happy and not leaving to swear to someone else.
In the beginning went all the way to the top, later they changed it to where only 10% of what a patron received would be passed up to their patron so only a couple above got any meaningful amount. A member could have a max of 12 people sworn to them so total amount being passed up could be very nice.
