If you don't mind me asking why Nasuverse ? Have they been wanked outside of comic-vine?
The big problem is that alot of people tend to go overboard with certain feats and put them on scales they aren't actually at.
I've seen people push for Universal Artoria and LB6 Morgan despite there being no real ground for it, I've seen people in VSB constantly stick with Multiversal Moon Cell despite Fate/Extella completely destroying that(It doesn't help the translation by Mirror Moon took everything stated as far reaching as they could vs. other translations which doesn't) only to then act as if there's a massive difference between Moon Cell and Earth Servants(There isn't).
Now you have people going apopletic over the extremely mid feats from the Tsukihime Remake(Outside of the ACTUAL impressive ones) now stating the series is on top of Shiki Tohno can somehow kill Servants with ease now due to completely misinterpreting everything about Vlov and the abilities of a Dead Apostle Ancestor and you rarely have people actually bring up what the Remake made more impressive(The DAA Principle being equal to a Divine Spirit's Authority(People tend to mix this up with Power when it's more definitive hax) and Ciel being able to take 3 of them without going insane, Calvarro Star in it's entirety, Arcueid in her Luminous Form).
And then, you have the typical Nasu fan who downplays it all because "the series is convoluted"(It's not anymore convoluted than other long running series) or "Too many authors make it difficult to see where the feats are"(They don't, hell, Nasu tends to encourage authors to go nuts with the setting, the abilities of Servants and their scale which tend to go against them being weak as hell) and other such easily discredited nonsense. I wasn't joking when I said Nasuverse fans should be on the list, when you have a franchise that has everyone hate entire aspects of it(Plenty are Tsukihime Fans that hate that Fate is more popular, you have Fate fans that don't understand why Tsukihime was ever popular, both groups hate FGO for keeping Nasu from making other projects and FGO fans hate them for acting as if FGO isn't a true "Nasu Project" because it's gacha and then you have the sub series themselves like there is now backlash against Fate/Zero due to how badly Urobuchi mangled Saber and how Kiritsugu fanboys tend to get his character completely wrong, etc, etc.)
