Didnt try new save, but in my old one i noticed very small amount of new armor mostly for batannians. And some changes on values on certain pieces. Barely bit more armor on traders. Still none vlandian, outside helmets.
Ik haven't noticed any changes. I've just taken out Garios' 800 man army with my 350 men and there was not one good piece of armor to be had. I have only one piece of t6 armor and that's "Rough Tied Bracer" you'll find anywhere. Oh and I have a decent helmet from a tourney. Managed to buy some sturgian lamellar (the one the shock troops wear, not the plate one worn by the heavy infantry) in a sturgian city, but that's it and I own three cities and have over a million now.
