looking back at this personally I think it's fine as a buildup, it's a lot more flowy than the kiai and for the reasons I already said in the comment above, so resolving for now

00:03:192 - to 00:24:062 - I think the density here is fine; it is a pretty intense part of the song, a lot of the 1/2 follows the piano which is important and there's 2/1 sliders separating the 1/2 sections
00:24:062 - to 00:34:497 - removed a lot of 1/2 notes following vocals, nerfed spacing from 1.2x to 1.0x (not that much of a difference but it's a calmer part)
00:34:497 - to 00:44:931 - removed some 1/2 notes following vocals, replaced with 1/1 sliders
00:44:931 - to 00:55:366 - although dense with 1/2, I don't want to remove anything since all the notes fall on important piano/vocals, plus there's a lot of breaks in between the 1/2
00:55:366 - to 01:05:801 - removed some 1/2 notes following vocals, replaced with 1/1 sliders

applied both

removed 03:26:311 (3) -

nerfed 02:55:053 (7,8) - and 03:50:214 (3,4) - to 1.2x

yep applied

yep understandable, I thought it might be a problem when I was creating this diff but figured it represented the song and vocals well so I left it. I still think 01:41:118 (1) - is more intense than 01:44:214 (1) - (and the other instances) simply because it is held for longer, so I nerfed the sv to 1.5x and made these sliders into C shapes instead so it's much less awkward and walkable

from 01:16:343 - to 01:28:731 - made walks 1.2x, dashes 1.6x, and added a couple more dashes
from 01:28:731 - to 01:41:118 - since it's a little stronger than the previous cooldown, made walks 1.3x and dashes 1.7x (with 1.3x its a little edgy to walk; I think most would read it as a dash and the 1.7x dashes are on stronger vocals so I think it fits anyways, could always nerf it back to 1.2x if necessary)

similar patterning/reasoning for 02:05:892 - to 02:30:666 -

went through the map and changed a few patterns from anti-flow to flow, I think there's a good balance now but feel free to re-open if there needs to be more changes

made them both horizontal and flow into the next object
