So...this has been a long time coming
This revision is based on this blog that we currently use to justify the shinza ratings.
Now, I'm not going to touch the 1A stuff cause that should work due to taikyoku being an absolute law regardless of the number of dimensions within the picture.
That, and this as another piece of evidence:
Black and White, Blue and Red, Light and Darkness, Obverse and Reverse. Every single conceiveable, Dualistic, conflicting, rivalring phenomena, concepts, that exist within this world, all without exception existed here. Flowing, in continous change, a Great Mandala in the shape of a designed pattern, changing in a kaleidoscope like form while continuing to revolve. Infinite colours overflowed, and nevertheless, there was not a single independent thing here. They all have an enemy (furigana: couple), that always certain, under the auspices of the absolute Law. Quite like a microcosm of their universe. An embodiment of the world of Dualism, woven in textile of trascendent scope.
So, the 1A rating would stay.
The main issue is High 1A.
Going back to the blog, we'll go to the explanation they have for the singularity being this sort of hierarchy.
"Next is the Singularity, the singularity is a tear in reality to the Throne where the godhead resides. Usually generated by a clash of Hadou Atziluth-Tai between the Throne and the lowest floor (Multiverse). Basically singularities are created from the collision between the "Color" or Law of Hadou Gods, the world is "unaffected" by the Law of the Hadou where God does not exist and is not affected by the Law as they block the flow of Law and became the Singularity rather than be influenced by the Supreme Law (Atziluth-Tai). In order to reach the throne, the challenger may opt to drill through the depths of the Singularity using their law.
The depth of the Singularity varies in accordance with the ruling deity's law strength (Taikyoku/Taiji). As such, Singularities generated by a God with "higher" quality would be immeasurably "deeper" than those of lower quality, and therefore will not be "drilled" or "crossed" without adequate strength - there are few exceptions to this rule, however.
Additionally, the Singularity is described as an infinite abyss of colorless Taikyoku/Taiji that can be comprehended and interacted only by deities. It is a "place" that gives birth natural laws and new ideas/concepts, and where the afterimages or shades of Gods from the past, who must be overcome and thoroughly understood in order to reach the throne, reside.
Despite being referred to as "place", It is utterly impossible to define the Singularity due to its abstract nature: the laws of physics simply do not exist in the Singularity, and all of creation are mixed there, side by side - be it past, present or future. Thus, the process of "drilling" can be compared to "falling" to nowhere.
Lastly, It should also be noted that despite being naturally unaffected by the laws of the Gods, the Singularity is still under the possession of the Throne God."
The first issue is that while the singularity itself might be below the gods, the influence gods hold over it allows it to become larger than other gods. We even have other gods taking thousands of years just to break a single layer of Hajun's singularity even after nearly all of it was drill through by Hajun
Thousands of years, tens of thousands of years, Shinsu, which continued falling, finally had the last wall severed and connected to the bottom of the hole
Note: This is after Yato states that the singularity was reduced to a single layer. But even at the beginning of the fight, it was stated that they were "near" the bottom of the hole, which they then state again
And obviously, we have the stuff with Yato being unable to reach the bottom of the throne even after 8000 years.
“That thing sits in the depth that is unreachable, not even after hundreds, thousands of years or even more”
Note that, however, Yato would have definitely reached the bottom eventually as shown by this statement
I can feel it, The Throne's location. It is very close.
Statement's at 7:27
This would actually now go against the logic of a stronger god's singularity being endlessly deeper than a weaker god's singularity as there would no longer be enough basis. Yato is capable of reaching the bottom as there are enough statements confirming that. And there isn't really enough context behind the statement by Mercurius to really say that it supports that kind of interpretation. At most, I can see the singularity being some sort of endlessly layered 1A hierarchy, but only using those two scans seems like quite a reach.
Another issue is with the throne. Currently, we give a High 1A rating for the Throne due to it apparently being beyond all the expansions of the singularity. This would imply that the throne is non-static in nature. This, however, isn't true at all.
The throne by nature is also supposed to be able to handle any god's spiritual mass, but can somehow be easily destroyed by any of them?? I hope I don't need to point out how contradictory that logic is.
This would therefore make throne varying degrees of 1A, and the gods as well due to scaling to that.
The other thing is for the gods scaling to the throne.
To be frank, I think we need to clarify that the gods would only scale to thrones belonging to the throne god that they scale to or above. For example, Ren, Reinhard, and Mercurius were all capable of affecting the Throne in many ways throughout their fight whether it was shaking it, freezing it, or outright destroying it. However, a stronger throne would likely be much harder to destroy, just like how a stronger singularity would be much harder to cross.
Manipulation of slashes and its targets through change and convergence. Those who were struck by Soujirou possesses the fact "that the sword called Mibu Soujirou cut them". Through this, he can activate the attack again and kill anyone without lifting a finger. Moreover while he can't change the absolute truth that "he cut something", he is capable of changing "what was cut". This allows him to knit the strongest slash by gathering all cuts he mades as a human and realize it, creating an attack that's strong enough to cut the Throne itself
We use this as well. Unfortunately, it also removes the important thing that soujirou is also capable of negating taikyoku differences with his slash, therefore making it almost impossible to use this for scaling. It's also especially hard to scale this feat to any other character due to the vocabulary they use like "strongest slash"...not sure if I have to clarify on why this is a problem.
And then we have Hajun, for some reason, having an "infinitely-layered" singularity. And, if I remember correctly, this is due to the argument that Hajun's value is beyond even infinity.
However, this has a few issues
This has never once been stated
His value is literally stated to just be a constantly rising value, hence why he's immeasurable.
So, even if all else fails, the gods would still have to be downgraded to 1A+.
The singularity of a stronger god can surpass a weaker god's level of existence entirely due to the influence of the throne god, even if the singularity by itself is nothing to them.
The difference between a singularity of a stronger god and that of a weaker god is not some kind of 1A transcendence, but is just an uncountably infinite difference at best.
The Throne, which is one of the main things we use to grant the High 1A rating for the gods, is not beyond all expansions of the 1A singularity, and would also be varying degrees of 1A.
Note: Sorry if it's kinda messy, I was rushing to make something and didn't just want to say "hey guys, let's downgrade the verse before nuking it from the wiki". Basically, I wanted to at least put some arguments or reasoning her for a downgrade
