At first when I saw that the hordes cannot stay too close ot each other as they woudl start fighting and so create attrition I thought ok , seems cool ... but when the game progresses this heavily penalizes the Chaos making too difficult to complete a game because the AI always spawns several armies and chase you with several of them and you cannot fight back with one single horde and even if you mass stack 2 or more of yours you can make one battle then you have the armies decimated by the battle and the attrition and the other AI stacks will destroy you , so I think this feature needs to be mitigated somehow or removed , Perhaps a solution could be to make the hords able to host up to 40 units instead of just 20 , after all its an horde and not an army !
