and 2 other things

i will make the experience counting much more on the battlefield , that will help the AI too ( that usually field experienced troops ) , usually i dont see ont the battlefield an enormous difference between green and veterans and its unrealistic

Also i will make units less vulnerable to rear attacks .. otherwise the game is all a "i block you with one unit and attack in the rear with cavalry !!" , that should help AI armies alot and force playes to work with infantry tactics .
