We have played several games with the banners of war and for us, no unit has been over powered.Yes they are powerfull if the others let you get in control of cities that gives you tactics cards and if you aim to get many of those cards.
but for us, especially the deamon player used many of his "cavalary" (dont recall teh names) to soak up most of the damage and then force him to retreat.
