I think it's silly, because a player army of 4-6 knights can dispatch of a full stack of this kind of army, and even walk away with all the cav units at half strength. At least i do so with the french. I once took out a full stack of archers, pav xbows and artillery with 2 feudal knights, a Noble knight and a Knight of Santiago (i must admit i was fighting downhill) and suffered less than half casaualties. Nerf passive ai bug and perfect charges.
