Overall: The current ARs are fine in my opinion; I don't believe they pose any issues in their current state.
Easy: No changes were made to avoid overlapping in some sliders.
Hard: I'm keeping the current OD since the map has a high note density, and I want to keep it easier for players who aren't as comfortable with hitting that many notes.
Insane: I don't see any compelling reason to adjust these values.
Illusion: Changed OD from 9 to 8.8.
