Okay, going to progressively respond to stuff here- this may take a few days so shit may not be accurate to the current arguments. I'll try to prune this of irrelevant information if it comes down to certain points being ignored/debunked/removed/what have you.
I don't understand the OP's point about statistics reduction. It shows dropping a guy in a fish tank, and I'm vaguely aware of Magi's concept of new god on top of current god ad infinitum, but I don't see any mention in the scan of actually reducing that guy's rank.
I cannot confirm the Japanese (?) translations, but I know these are always a point of contention in weeb stuff. We may want to bring on one of our outside translator, if these aren't already officially translated. However, even if it were translated as OP suggests, I don't see how it actually changes anything about the apparent misconception- they change the order by ascending. Without evidence of just arbitrarily placing themselves wherever they like, I hardly find such a claim justified. I have read the translated scans (although I must admit using a mix of translated scans and untranslated raws seems odd to me), I don't find them to be strong evidence of the claims presented, either. Any ascension or descent would effectively change or alter the hierarchy of the gods just as much as ten thousand ascensions or descents.
I will also say, regarding these scans, that some of the fonts are really inconsistent, and some push in many words in tight boxes- is it possible these are fan translations of some kind? Just seems odd, is all.
Painto12 seems to bring up the same point I did, in that the OP doesn't provide evidence of being able to arbitrarily swap ranks. He also provides a scan that seems to visually imply it is one by one rather than swapping out at any point? Everything seems really interpretive from this point on, I don't think either party is more right. I would also like to note that the phrase "a god above gods" is being harped on quite a lot- I think that's silly, frankly. You can be the third lowest rung on the infinite ladder and still be a "god above gods"- it isn't evidence of anything.
Ant at one point said "Well, to me it all seems too muddled and unspecific for our purposes". I agree, for the powers being argued for are incredibly vague and never defined concretely even within the scans provided by the OP. They can change places in the hierarchy, sure- the exact mechanics of this seem undefined.
This scan is interesting, provided by Thanatos, and seems to be the first thing that would begin to defend the argument of the OP. However it is cut off. If we were told who (of the characters mentioned in the scan) were in what positions in the Hierarchy, then we would definitively have proof of the OP's claim. I admit this is an implication, but still not sufficient evidence for my tastes. Similarly, though,
this scan does imply the very opposite- the gods are linear in their transcendence, one by one. I know people disagree with that, but it doesn't really matter. I feel I'm more in the linear progression camp right now.
I think that about summarizes my understanding of the thread. Personally, I'm against what is suggested by the OP- the changes would be sweeping, would upgrade characters tremendously, and bears very little evidence over the current ratings. That's my evaluation.
