To summarize as simply as possible:
The map has patterns and flow that do not belong in a song of this nature. AXION is not a powerful song. It is not a song that implies, when listening to it, fullscreen 1/4 jumps, regardless of whether or not they are playable.
The issue is that the higher difficulties are taking the music's beat patterns and applying patterns that do not belong with the music, do not fit the music's tempo, buildup, or power in any predictable or comfortable way.
While the individual patterns are possible and playable, the difficulty of them are all over the place and do not fit the theme of the song - which progressively builds up to "max energy" about 50% of the way in, before rapidly declining in the final 1/4th of the song. These patterns do not fit AXION. There are other songs where they can totally fit. Furioso melodia has a lower bpm but much, much, much higher intensity.
We should really find a good english-> chinese and chinese->english translator to facilitate this. Believe it or not, I want this to get ranked - but as it is right now it is simply a bunch of big name Chinese mappers throwing random patterns that look fancy at a song that cannot withstand the strain.
This is, to a point, up to the mapper to interpret. Two different mappers can certainly think a song is different in intensity. But making crazy 1/4 jumps across the stream and back and forth 1/4 streams should be something mappers find a good song for - they shouldn't be putting it in the closest track they can find.
All of these mappers are quite good. They're very good at mapping, I won't deny that, and I respect each one of them a lot - but this kind of "crazy mapping" is something most self-respecting mappers stopped doing early on as it is a newbie fantasy.
Please do not disregard this post as this is about as respectful as I can get - I don't do "politics" very well.
tl;dr the song choice is much more of an issue than the actual mapping or the patterns within them
