HR is a mod that everyone knows about, since it is one of the seven difficulty mods in the ncreasing Osu! Standard gamemode, but most times, i found HR to be very frustrating since it both decreases the CS and increases the AR, making a very tricky combo, and ive thought about this for a long time, byut i believe there could be new mods to just increase the AR, CS, OD, and HD. It would defeat the purpose of having some mods, but there could be limits to it, such as decreasing your score. in truth though, i dont know how this feature will be implemented into osu if it makes it in.
