He is saying Svin quite explicitly reacting to lightning magecraft is "Overhyped" too.
I don't understand how it's overhyped by any means considering the narration of what Svin did and what the Manga shows us unless he wants to pretend ONLY Svin can dodge Lightning which is wrong in it's face as we got the Melty Blood Manga of Shiki Tohno doing the same thing and Gray dodging Lightning twice.
At some point people probably going to use Rin beating Medea with her punches as a prove that Servants are physically weak. Actually some people already does I think.
Yeah they do, why you think they believe Mahoraga can destroy Berserker in physical combat or most street tier characters can bypass God Hand with a punch because they ONLY believe what the text tells them exactly with not even trying to actually think and use their brains and scale that shit further.
They fully believe if you sneeze on a Servant, they die and they are pissed off that recent Fate Media shits on that idea which is why they constantly stick with Fate/Stay Night or Fate/Zero now.
