How are line-ups decided for Kingdom Raids?
Kings and Sentinels are always included, squires always excluded, then we fill the remaining players to get up to the 10 required.
For remaining players, we order all players by difficulty (depending on the defensive score per building), and then split the players into 3 groups: easy, medium and hard by taking the first 30% of the order list as being easy, next 30% medium and remaining are hard, then we try to fill the 10 players with the first 3 picks from the easy split, next 3 picks from medium and remaining 3 for hard.
