I like the idea, the mod slowly but steadily becomes boring to me.
And maybe half of the kingsguard could be replaced every round by top scoring (damage dealt) peasants or something. Although, this would make poor xbomen and archers screwed, they would forever remain peasants, and as peasants they are useless, especially having in mind prices of xbows. Which additionally sucks, because we don't have that moment where kingsguard has to protect the king with their shields and ultimately their bodies, because range would suck big time.
And I don't think the king should be helpless, he should be allowed to defend himself if he wants, but his equipment choices should also be limited to top tier weapons, cause it would be stupid if we had kings defending with pitchforks and sickles. And definitely no shield. Also, it would be very cool, if unrealistic, if we could vote for kings for the next round, because it would be the best if the persons playing kings would be the most hated people in the community.
