I really like the diffspike from 04:42:706 onwards but it almost makes the entire thing before it look like futsuu (apart from the obvious exceptions such as 03:54:703 - and 02:43:397 - )
For example why cant the pre-kiai intense parts use more cool concepts such as and 02:43:397 -, i think this part is wonderfully made and it seems like its the only one in the pre-drop
01:11:629 - here you except an epic start to the map and all this 10,5* offers here is just a bunch of relatively easy streams, wouldnt some 1/6 improvs here make a lot of sense, maybe at places like 01:12:575 - , 01:13:656 - and so on. This could especially be done on the second half of the streams starting at 01:28:927 - since this part only differs in featuring longer (although still 1/4 only streams)
02:54:669 - and 03:06:306 - is alright density but i feel like you ought to make it more dense for reasons mentioned above
this is just what stood out to me the most while playing the map personally and i would love to see this map try out more, i also think the map would greatly benefit from at least some degree of consistent difficulty but if you disagree with the modpost then just resolve it
btw if you feel like im not expressing myself clearly enough i can elaborate more
I partly agree with you, this map heavily gets its higher SR because of the obvious difficulty spikes, but I feel like the song doesn't support that much in what you call the "pre-drop".
I think the 1/6 improv is a cool idea, but that would be overmapping to me, which is something I wanted to avoid in this map because I didn't want anyone to think this was overmapped just to make it high SR. I am also not a fan of overmapped maps in ranked. Some improv like you mentioned around ~1:10-1:40 might be okay though!
Would love to have more opinions on this, I personally don't think it's an issue if there's a difficulty spike if the song is just made like that, but I can understand it from a balancing perspective.
