This thing always annoyed the shit out of me, we are proud that c-rpg is quitte the opposite of native , yet we keep some native armour names.
I suggest this.
Sarranid to Saracen
e.g Sarranind Guard Armour to Saracen Guard Armour
Khergit to Mongol
e.g Khergit Elite Armour to Mongol Elite Armour
Vaegir to Rus or Druzhina
e.g Vaegir Elite Armor to Rus Elite armour or Druzhina Elite armour
Also the Strange armours should be renamed to Samurai armours.
I know that these arent some serious game changing addons, but it improves the immersion a LOT.
