I'm not an osu!-BAT, neither am I fully skilled player in this mode, which is why some points might be at some way wrong. But I would still like to say something about this topic.
Pretty long post, huh? Sorry if anything I said might be totally wrong. After all, I'm rather a Taiko Mapper / Modder.
- In my opinion we should give this a go, not only because this map-set has been unranked 3 weeks ago.
I understand the purpose of the unrank, especially when we look into the future; preventing people to use this map as example to justify their "burai-sliders", which, if I'm honest, in this case really isn't a big problem at all. I didn't read yet that this is something considered as extrem case and I don't see it either as one. Beside that, I played the map now the very first time, and even for me it was pretty much clear where that slider is going(maybe because you notice for a really short amount of time in what direction it expands?). So at this point I would rather prefere to give the slider a go, instead of keeping it unranked because of similar cases which are possible in the future. Makes me come to the next point... - I'm a Taiko mapper, and patterns are for us really important, especially how they work to the music. Thumb of rule is to see if the pattern sound(placement), look and plays well. In osu I guess, the sound isn't that important at all, but looking at the placement, the slider does fit well to the song's flow, considering its shape to it. Additional to this, playwise it isn't that tricky at all as I mentioned above. I can't explain it as good as some of you guys can do, but it looks pretty clear where this slider is actually going.
About the look of the slider we can argue I guess. But in this case, it should be up to the mapper since it isn't anything that is absolutley considered as ugly or a no-go(that's why I think it's no problem for further mapping. If something really atrocious happens in the future, we can stop that really easily. Community does help in this matter sometimes as well). In this case, it's the mappers own fault if people rate the map bad because they dislike the slider. It will also scratch on the mappers image, but that's not something we should deal with.
I can share concerns about a map as whole, but not because of one single slider(in this case two), while everything else seems to be okay. Asking mapper to take care of this next time helps in my opinion more as enforcing many things everytime. - Beside the mapping way, I also want to mention the behavior of the mapper and the song itself. The mapper probably didn't response always in a nice or for other people logical way - in other words: beeing stubborn. But if you ask me, we have to look at the overall picture.
Letting this unranked because of one single slider, prevents us of having more genres in a game which is ruled by TV Size maps or other similar genres.
We do not have often such songs compared to anime themes, which is why I think it would be a waste letting it unranked. It is also a pitty for the players (AND TAIKO).
Two BATs who approve this already: p/3257668 , p/3259450 - One last word from me:
In case some BAT still say this must stay unranked(which I probably wouldn't understand with my current knowledge), I could add only one thing I would critizies about: The so called "burai-sliders" are placed on different stanzas which gives me a questionmark. 00:55:182 (1) - Here it's at the beginning of the kiai (first stanza) while 01:42:078 (1) - appears in the second one. What confuses me even more is the fact that at 01:06:216 (1) - no "burai"-slider" appears, even though it's the same sounding and a similar stanza constellation. Same applies to the part at 01:50:354.
That would be the only reason for me, either to remove them or add at said timelines new "burai-sliders".
