I feel as if AR6.5 still makes this a memory map instead of challenging reading. Given the aim/control requirements the map has, understanding the hex patterns, stacks and beat gaps on the first try (or even first couple of tries) is out of reach for pretty much any player out there. AR8 makes it pretty comfortable in comparison , even with me having memorized the map already, and I wouldn't recommend lowering it much more than that. I wouldn't worry about HR players, either - the end is hard enough to make nomod/HD plays viable for #1 for a good while after the map is ranked.
