Don't blame Kyshiro for stirring up a debate/discussion about the difficulty name just because he wants to expres his love and chose to do it this way. I'd honestly blame Loctav for nitpicking everything and unqualifying something like this, for this reason, it's just asking for it. Like the post above me said, it indicates the difficulty and it's the hardest difficulty of the song, the rules clearly say that the mapper can use a difficulty name they like. So, because there's a name, an expression of love, or maybe just because someone else decides that his dedicated love songs maps difficulty names are masterrace, does that mean that a word, name or anything of the kind has decreased the quality of the map and is worth of this unqualify?
Map follows the rules and guidelines, Loctav, so maybe that's why nobody pressed the button yet. Did you think about that?
edit: other posts above me now, lel.
@Sakura: I think a debate about this has been before already too. The rule was set in place because of the difficulties like CRN and Skystar. That's how they formuled the sentence, and you're taking it way too literal.
