@RedlineAlchemist Armor is overrated, in actual wars only an extreme minority would actually use complete sets of armor.
Those things were so expenive that small countries would actually get into debt to pay for such armors for their elite troops.
It was way more common to see people wearing light armor sets, or even just a breastplate a couple of gauntlets and armor for the legs, because they couldn't afford more. So I don't get why is it that much of a problem to use innefficient armor.
She's an elite, she's fully confident that she won't let either arrow or sword get though her defenses so full armor would be a waste. This is possible because it's a fantasy, people CAN become that strong.
And even if a stronger fighter showed up and beat her, it certainly wouldn't be because she wasn't wearing full armor. Because you can deal with full armor by just immobilizing the enemy and sitcking a dagger between their armor joints. That's the main reason why Daggers were usually referred to as armor killers A better fighter would do this as easily as simply overpowering her and hitting her belly.
