Exactly, there is a reason why I mention Environmental damage. Even the Bellerophon vs Excalibur mentioned, just the fact that its huge beam of energy vs another huge beam of energy in the form of a horse should destroy the building they were at when battling in F/SN but it didn't.
To be fair, Medusa was fighting Artoria at the very top of the skyscraper and Medusa was aiming precisely at her, not the building itself and even THAT caused massive gouges in the building itself.
But like I said before if they actually gave a shit about physics and otherwise, they would realize that Saber's Mana Bursts and Excalibur Morgan among many other Noble Phantasms giving off the absurd heat and energy they do even BEFORE they hit their target would clearly show just how powerful they are with just the offset energy, let alone the actual energy itself... but nope.
But we know they can. F/SN just didn't show much environmental damage which is what people latch on to, when they want to say F/SN feat are not that impressive and F/GO is massive boost.
The thing about that at the end of the day is that environmental damage literally doesn't matter in the slightest in any series and judging series based on that is fucking insane.
Like you don't even need to count something like DBZ where every attack after Frieza should destroy the Planet hundreds of times over but doesn't, you can point to shit like Fairy Tail, Undead Unluck, One Punch Man, etc, and see no series is ever consistent with environmental damage meaning shit for many reasons.
So... he's using a dictionary because of what someone said on her being bloodthirsty... meaning she's completely insane? He does realize that just because you can fit a term, doesn't mean you are that term 100%. And if she was that bloodthirsty that it basically made her that vulnerable, not only would they have talked about it in advance, she shouldn't even be able to go to "Zero" in the first place.
EDIT: Seriously, this is why even in Reddit, people like this would get made fun of until they straighten themselves out or be ghosted by everyone else. I can literally pick ANY of the times Musashi meets someone and you can see she's extremely rational even when she wants to fight someone. I don't even know where the "Bloodthirsty" comment came from as she is literally no different than Goku in her wanting to fight someone.
