hi, as a dude who has a Very Different Mapping Style from Mir, hopefully i can shed another perspective on the issues the map has. This is all for ReTraumend.
Please note that I think this map is trying for something nice, but it just needs help. It's not a bad map, it just has some major flaws people can see but can't really explain well. Because most people suck at modding.
Again, this seems to be an issue of "Placing patterns over the music rather than with the music." Although this map tries very hard and often succeeds, it has many flaws that a lot of people can see but not many can explain.
The map itself is fine. It's clean and structured well - but it's not structured the way the music is. This is something that is very very obvious to any experienced mapper or modder, but it's hard for players to care or notice and it's hard to explain to less experienced mappers and modders.
For example, 00:02:627 (1,2,3,4,5,1,2,3,4,5,1,2,3,4,5) - is a very nice set of patterns. however, the music itself actually skips over a beat on 00:04:205 - specifically to drop emphasis so that the third pattern can come back up in pitch. You actually showed this in both the hitsounding and the pattern of movement - the first pattern is a zig-zag, the second is a counterclockwise loop, the third is another zig-zag. But the extra click can really stick out and makes all three patterns "look" the same, even if they aren't. You're being too subtle, basically. Even something as simple as replacing 00:04:048 (2,3) - with a 1/2 slider that blankets 00:04:837 (5) - can bring the entire pattern into the light and really clarify what you're going for.
When you're mapping with additive hitsounds and rhythms, you need to be very careful and very obvious. That comment above was the first fucking three patterns of the map, and got a paragraph explaining why changing two circles into a slider would be a good idea. It's no wonder most people wouldn't want to go over the entire song and try to explain what they feel could be improved. Especially since eLy is very stubborn and doesn't like to change 'just because someone said so', and especially since most modders, even in the BN and QAT, could not mod like this.
This gets far harder and more complicated the further you go into the map - eLy keeps adding more to the melody and supplementing what's already there, but makes some mistakes (Either from just putting in patterns that don't quite fit what the music structure is, or ignoring the musical patterns outright) in following the structure of the song and while it's extremely hard to just select a pile of notes and say 'this is wrong/off', it's extremely easy to feel that "something here is off" and that's why you get a lot of objections from this.
This kind of thing is subtle and very hard to pin down, and never appears in most mods because it's actually quite hard to just select a pile of notes and go "fix it by doing this" - it's a conceptual problem and the language barriers don't help at all.
And yes, this kind of "problem" with mapping mostly doesn't even exist in most asian circles (the shear concept of "maps should satisfy mappers too, not just players" is utterly alien to their general mindset while mapping) - it's one of the major problems the asian and european mapping communities have with eachother's maps - but this is a global game and people should discuss their differences as best they can rather than segregate themselves into two parties.
