Why Siriel downplay Nasuland this hard ? its seems personal at this point.
The Spacebattles Special...
But no seriously, Siriel loves downplaying it for who knows what reason but it's been well known for years that he downplays the shit out of it despite knowing and reading the series and being up to date.
It's why you get that absolutely stupid shit about Gilgamesh "having a coin flip on who he wins and loses to" but ignores the fact that Gilgamesh's losses are due to his arrogance and being a fool... in ONLY two routes:
One is against Shirou, the other is not realizing Sakura was basically an Anti-Servant Monstrosity. His loss against Saber was a literal fluke that wouldn't have mattered anyway because he had no way of dealing with Avalon in any fashion even if he used SNI and saw it coming.
Outside of that, his losses in FGO was in the Fate/Zero Accel Event where the whole purpose was him accepting Berserker Lancelot's challenge... then IMMEDIATELY jumping him with:
Artoria Pendragon, Diarmuid, Zhuge Liang/Waver Velvet, Mash Kyrielight and Ritsuka and their Shadow Servants... and Artoria explicitly has Irisviel, the literal Holy Grail, as a Master.
...Can you blame Gilgamesh for losing that fight? Especially when Berserker Lancelot alone is actually really fucking strong and tends to be downplayed in his strengths? Let alone a fully powered Artoria that can become Salter if she chooses?
And the other time was in Strange Fake which required Ishtar to find the false Key to GoB, be able to make it BECOME the real key and lock the Vault at the perfect time that Gilgamesh gets fucked over by both Humbaba AND Alcides at the same time?
That's what a lack of context does to motherfuckers, not helped by the fact that you have dudes easily believing it because that's also what they want to believe.
