I'm slowly starting to feel like going a cav archer horde was maybe not a great idea. After fighting in tournaments and seeing how terrible AI is with mounts and seeing how badly they perform in the field compared to peasants I'm really concerned I just wasted a ton of money on cav archers. I'm using Khuzait cav archers right now, a few battles ago I watched a group of 20 cav archers run in circles around a fleeing looter for a full minute without killing him. How well are your cavalry serving you and what faction/troop tree did you go for?
