No HR is definitely not harder than DT on most maps, its just in par with HR.
on high bpm maps DT is harder than HR, maps with weird patterns (such as fruits being close/silly hyperdashes appearing everywhere)
on a side note HR definitely does make a map harder, you'll need better reflexes and better ryuuta control over it.
also, are you seriously talking about Hatsune Miku in here? tell me, how long before he got banned? get your facts straight before you post something.
P.S. I didn't notice Drafura's mod multiplier but I definitely support that, but most likely impossible to happen, as for now that is.
Edit: AR hackers aren't really hard to detect, on contrast to FL, on hard maps that is. You'll know someone who hacks when you get common sense, its a great skill to have, and most of you don't even have it.
