Sure I know this isn't entirely related, but it really bugged me. The Blades Armor is closer to Roman Lorica Segmentia than anything oriental. I cant speak for the Bracers, Sabatons and Helm though. Or the Shield for that matter. it just looks like a stylized round shield, possibly covered with metal sheeting. The Most common shields were Oak or Hickory planks, with a metal band and metal sheeting over the face. Better to catch an arrow than deflect it into your partner. Same with spears/pilum/javalin.
Wasn't it established that the Akavir have much less skill forging/wearing armor? I read it in the book that describes the duel between the Emperors son and the Potentate's son. So I would expect the Blades to incorporate the superior weapons that were brought to Tamriel, but opt to wear their own armor.
Actually... I may have been way wrong. I can't remember, but I think the ghosts at Pale Pass had the same armor the Blades do. I guess it is Akaviri (is that the correct spelling for the adjective?) armor, which doesn't make a lot of sense to me, given what I wrote above.
