it's pretty dense yes, but it supposed to be mapped continuously until the chorus end
As the higher difficulty has denser intensity and the highest difficulty has the longest 1/4 stream here
and there're sounds that support 1/2 through, I'd find other rest places instead of removing this one
I think master diff here is irrelevant since it uses more difficult snapping
Also, the part starting from here 02:20:821 is significantly harder to handle imo but considering it's the fastest and hardest part, I don't think 02:30:989 needs any nerf since there're many 1/1 spaces that helps players gradually recover and is easier to handle than previous part
