This mod enables troops to bear the banner of their lord, with lore friendly and hand picked changes to the troop tree. Also, the Dragon Banner and the Campaign Banner are available at the shops to equip yourself or your companions.
Read more about the mod and it's changes in the mod description and the changes article in Nexus. Also, the technical aspects in the other article (that I may extend here if there's interest).
I invite you to contribute ideas to the troop changes, so as to improve the balance and even add some historical accuracy about who would carry banners during battles and what compromises would they see to their equipment.
