I'm a vassal of Khuzait and we're at war nonstop. We're the defacto leader of the entire map since everyone keeps declaring war on us. Our faction's power sits around +10,000. Originally it was the Vlandians but they got smothered after being at war with everyone for months.
What's annoying me is the fact that factions with as little power as 1,200 keep declaring war on us and there is no notification stating that we're now at war. I just find out as I'm leaving a town after trading and see a sea of red tailing me. The longest we've been at peace was like 4-5 days.
Also the wars are always in pairs. We make peace with one faction and continue fighting another. Then 1-3 days later another faction declares war.
