you REALLY need to get yourself a healer hero and a pathfinding/spotting hero. I use Jeremus and Brocha (or something liek that) as my 2 companions, then sometimes ill hire a warrior npc just for fun and suit him up really badass looking like a clone of me. I couldn't imagine playing without a healer or pathfinder, it would suck too much. Also get the main chunk of your army made out of swadian and vaeigers knights and khergit lancers. My personal army is half Swadian knights and half Khergit Lancers and they can run over any army with no problem at all. Don't mess around with infantry or archers until you get better at the game and know what youre doing
