When I started writing this I was quoting entire sections of DT's argument, but in the middle I realized it was getting too long, so I am just going to compress the quotes into descriptions of the feat/point being discussed.
I will say up front, I have not watched or read this series. In fact, I haven't heard of it before this, so I am just going on what each user said.
DT's Points:
Base Arei/Junko: I agree with DT. The fact that Junko is explicitly stated to be holding back and not taking the fight seriously makes it useless for scaling, and it really looks like Arei is just sort of getting her ass kicked here, so.
Enhance Arei/Junko: I agree, the propensity for Junko holding back makes her initial struggling more likely to just be a hiccup in the application of her power, then she realizes Arei is stronger and flattens her. I don't think it scales to the feat much.
Kuroko/Arei: Again, agree with DT. Arei was weakened, Kuroko doubted her ability to match her otherwise.
Anti-Feats: These all strike me as significant, but since it's not presented as the basis for a conclusion, I can't say I agree or disagree here.
Touma Explosion: I am not qualified to assess calc issues. DT is, so I trust his judgment, but I can't actually vote on this.
Touma/Tatemiya: I agree with DT's reasoning. Given the explanation given for how magic works, it is impossible to say that all of a characters attacks are the same strength, and the counter-argument about Styll's attacking being able to run directly through Touma makes the attempted scaling illogical.
Touma/Thor: I agree with DT, the feat doesn't scale.
Element Scaling: I agree with DT. It basically describes this group as slowly compromising the Element through "death by a thousand cuts." This would be like scaling base Aang and Katara to the Fire Nation drill because they spent a bunch of time weakening the girders. You can't scale them to this. They would need to be able to do it in one blow, not "blade after blade."
Touma/Vento: Pretty simple. I've seen like five characters up to this point enhance themselves with magic. Regardless of whether we know this explicitly with Vento, we shouldn't scale Touma to it given the immense uncertainty.
Itsuwa/Terra: Seems pretty simple. If he didn't say the chant then that probably wasn't the type of attack he used, and Touma straight up says it would kill him. Agree with DT.
Tobio: Easy agree. It'd be stupid to scale anyone to this if they haven't fought Tobio.
So, to summarize, I agree with basically all of DT's arguments whilst being neutral on the calc validity of the explosion feat. I can see how the inherent complexity of this verse obfuscates the details that compromise our ability to scale these characters that way. But, at the time that I am writing this sentence, I have not read the responses from the supporters. I will do so now.
XDragnoir's Points:
Junko's Other Feats: Haven't seen the feats, don't know why or if they should scale.
@DontTalkDT can you explain?
Anti-feat Rebuttals: I didn't use the anti-feats to form any conclusion, so I will skip this for now unless it becomes relevant later.
Vento: Regardless of whether Vento is stated to have such a mechanic, it is widespread in the verse and my understanding based on DT's post is that Vento does not have directly scaling to other characters, so I am not inclined to think it's relevant.
FantaRin's Points:
Vento: This appears to be the same as Dragnoir, so I defer to my response above.
Passive Thor Belt: Not necessarily the case. Equipment powers are not always passive.
Elements: I don't know what the AAA is, I cannot comment on that. However:
One was a girl in a suit of armor who wielded several swords, spears, and axes ...
... But none of it hit. Instead of keeping their distance or flying into the sky, the girls moved as close to the monster as they could, prevented it from moving, and cut off the carnivorous inchworm’s view to create blind spots. The girls sometimes slipped between its legs, circled behind it, ran up on top of it, and passed blade after blade through it.
To a hundred meter Element, a blade wielded by a human was nothing more than a toothpick.
But definite cracks formed. And they spread and grew.
By some twist of physics, the giant form fell apart even though they used no poison, electric currents, or bloodsucking.
I get the strong impression upon reading this that these girls used their agility to avoid the Elements attacks while slowly compromising it with attacks that were relatively small/insignificant to the Element, but which added up to accumulate to defeating the monster. I categorically reject using this to scale any of these girls to one of these massive beasts destroying a house.
The Heat of Stiyl's Sword which, if likened to Taco Bell sauce packets, is easily "Diablo" level or higher: I'm not familiar with the interaction of extreme heat and how it might negate durability, but I had other problems with this scaling aside from the Stiyl antifeat, so I suppose it is somewhat moot.
Overall though, it's clear that I strongly agree with DontTalk.
