Hard
AR: 8.2 -> 7.5 - 8
OD: 7 -> 6 - 6.5
Insane
OD: 8.5 -> 7.5 - 8
Apeirophobia
OD: 9.4 -> 9 - 9.2
These changes are aimed to make the gameplay more a bit forgiving because such high OD values (and AR on Hard) aren't really required at this bpm and density in the respective diffs.
Edit: Turns out that OD on top diff has been lowered already, keeping it in for BN-App anyway cuz it might look silly if I write in the general general tab for... 2 diff adjustments instead of "almost the whole spread"
