Well, first of all, I find funny what was said earlier about "standards changing and not being 2014 anymore", since difficulty name regulation was something we pushed for discussion back in the day. I was, personally, one of the BATs who were more bothered by this when difficulty names actually made no sense at all. However, in my opion, that's not the case for this map, I believe the actual difficulty names actually show progression and they are fine for ranking. On top of that, the mapset has 3 difficulties which leaves no space for "wondering" which one is the easiest, hardest and inbetween difficulty, not implying that the difficulty names aren't clear enough but just in case newbies were the problem.
The thing with difficulty names is that, for some people, not even the standard ones "show indication of difficulty" I mean, can we get the team agreeing on what's a "Normal"?. That said, it's impossible to "rule" over difficulty names with some sort of "standard criteria", that's a part of metadata that will always require case by case analysis and a little common sense when modding. Take the example of Xanandra's map, which was quoted in this thread, that map had over 4 difficulties with custom, iffy, random names in a foreign language (not to us). That clearly needs some regulation and I have to completely agree with that disqualify, however definitely not with this case, we're talking about 2 completely different scenarios in which the same regulation was applied, that's wrong. Little tweaks to the names won't make any difference at all, this is just time wasting.
So, since the disqualify allows room for more discussion and discussion is happening, this has been productive. Nonetheless, discussion can't last forever, else beats the whole purpose of this system, a time limit should be set in which a decision should be taken. I personally believe, taking in account that this will always be a subjetive matter, that there's enough, elaborated, opinions on why this map should be re-qualified in it's current state and that's what should be done.
