That's three times you cited this example. I would like to name heroic lightly armoured heroes that got messily killed for being too reckless, but unfortunately the more common a thing is, the less it is put down with details like names in the annals. Chronics take note of unusual things.
Chronicles are an attempt to tell history, but in the end, they really are just stories about great figures doing unusual things. This is not only because readers find more interest in that, but also because larger-than-life characters really do succeed more and stir more people to their causes in reality as well as in fiction. What then does that say of your apparent strategy to play this game like a character as unworthy of note in the chronicles as possible? Read about Oda Nobunaga and his decision to fight the Battle of Okehazama, then tell me if the way you steer this character would have him making the same bold calls that put Oda in the Shogunate. What are we striving for the character to achieve in this story? This is a story, and all stories everywhere subscribe to one universal rule:
Rule of Cool. If our character dares, anything is possible.
And, actually, I
could name some lightly armoured "heroes" that died as a result. Harald Hardrada and his forces were killed without their armour on, and Julian the Apostate also died chasing a fleeing Parthian after a victorious battle without any armour. If you're gonna argue a side, then try to do it with a certain depth and command of facts, rather than "I would like to name someone like this, but I'll pretend it's impossible, because I really am not up to the task of doing it personally" Just because you didn't read about them doesn't mean that they didn't exist, or that their courage won them no glory before their end. They may have died from rash boldness, yes, but their daring and out-sized personalities where the reason they had the chance to be known in the first place, rather than dying unknown in a farm cottage.
And in closing, I will write you something from Beowulf:
Each of us all must face life's ending,
so win who may, glory ere death!
That is the warrior's worthiest doom.
