I have nothing against neck armour, but since it's a armours-complaining thread, I can't help but say that I'm strongy disgusted by Rus armour's pants (or lack of legz like in Druzhina Lamellar Armour or in Mongolian lamellars).
I would like to see legs in that armour covered with dark and mailed (for dark cuirasses) or lamellar (for Druzhina Lamellar) cuisses with shiny knee-guards (like in Transitional Armour) to match most steel greaves.
Also, I would like to see red-topped and blue-topped Nikolskoe Helm, and Rus Nobleman Helmet with red or gold top. And blue shirt, instead of green/brown under Lamellar Cuirass.
