One of the popular strategies was the formation of a huge meta-coalition from many kingdoms throughout the map, with the aim of combining victory points in the final. To do this, the “donor kingdoms" had to be in the top 10 on victory points. Then the main kingdom “stole” victory points from them (of course, by mutual agreement and without actual resistance). This, as you can understand, is contrary to the idea that lies at the heart of the function, and which is to maintain a competitive spirit until the last moments of the game round.
It turns out to be a korlevstvo donor can be if you bypass the rules.
