Wait, who am I kidding? I hate myself. Cutters have razors, I have you.
So what you are trying to say is that me casually using the term medieval as a catch-all for the period from Dark Ages to Renaissance (as it is also commonly used in games) is equivalent to using a 200 pound metal obelisk for a weapon? Eh?
I implied otherwise when I pointed out that colossal swords are still unrealistic whereas this sort of anachronistic but plausible get-up can still look cool. As can colossal swords, to be fair. The issue is that you, by implication, purported to be someone who "is into HEMA or history." Partially as an excuse for your inability to suspend disbelief of japanese fantasy tropes in a deliberate pastiche of disparate elements, which betrays a pretty sad mismanagement of expectations on your part, but also as a way to aggrandize yourself. And what I am pointing out, and what you are conceding, is that your pedantic interest is strictly superficial and extends to making completely banal statements like "buster swords are pretty dumb."
So in other words, most of what I am wearing IS a medieval knight's equipment, but in your effort to make a pointless point, I suppose you feel the need to sweep that under the carpet, so you can more easily focus on the one thing that doesn't fit.
It is not that there is "one thing" that does not fit, it is that the armor itself does not fit with the accessories (most of which are part of the armor set.) And it is precisely that there are
some elements that fit with each other and others that
do not that renders something eclectic. For the record, the most believable part of your character is the size of his head, which seems very authentic to his player.
My point, if you still don't get it, is that if you try to use the most basic understanding of a topic to immediately abandon any humility and bore the world with pedantry, there will always be someone who is even more of an insufferable pedant than you out there ready to do the same to you. And moreover, if your fledgling interest in history prevents you from suspending belief in fantasy, the only thing you are ultimately broadcasting is your lack of imagination.
Ah, lithium, lithium, what would you do without me...
The question is the answer.
