Current rule:
However, considering a series of recent discussions directly related to this rule (a couple of which can be followed here and here. The first discussion is particularly interesting since it's about a rule's gray area when it comes to application) I believe that this rule is outdated when considering the current mapping scenario. This is mostly because of three reasons:
This would be equivalent to the removal of the rule cited above from the Ranking Criteria.
This should be sufficient, since there is already another rule enforcing a clear progressive difficulty naming scheme for difficulties which do not belong to the highest level of a set:
If we consider difficulty names consisting only of usernames, these are typically not fully descriptive of their difficulty levels, so the rule above applies for them as well (for example, "Skystar" would not be allowed as a difficulty name for an Hard if there already is an Insane difficulty in the set).
A difficulty's name must not solely consist of one or more usernames. Words that happen to be usernames are acceptable within difficulty names as long as they relate to the song.As far as I recall (it's been a long time since this rule was introduced, so feel free to correct me if I am wrong) this rule was introduced to the Ranking Criteria in order to prevent the proliferation of mapsets in which the majority of difficulties were composed exclusively by usernames, with the consequence that the difficulty progression wasn't clear enough for many of these sets (an example of this would be the following set: https://osu.ppy.sh/beatmapsets/87547#osu/244802)
However, considering a series of recent discussions directly related to this rule (a couple of which can be followed here and here. The first discussion is particularly interesting since it's about a rule's gray area when it comes to application) I believe that this rule is outdated when considering the current mapping scenario. This is mostly because of three reasons:
- At this moment, the highest difficulty (or difficulty level for Insanes/Experts) of a mapset is already under no obligation of following a clear naming scheme for the difficulty progression. As such, there is already a big number of mapsets where Insane/Expert difficulties do NOT follow any classic difficulty naming scheme, using unrelated terms instead;
- As explained by some of the posts in the discussions I've linked above, some of these difficulty names (e.g. Arles) already have a preconceived notion of mapping style and difficulty in the osu! community, making them effectively descriptive of the difficulty in some cases;
- In general, the rule is worded in a way which makes its application unclear for a number of edge cases (one of which is present in the first discussion linked above).
This would be equivalent to the removal of the rule cited above from the Ranking Criteria.
This should be sufficient, since there is already another rule enforcing a clear progressive difficulty naming scheme for difficulties which do not belong to the highest level of a set:
Difficulty names in a beatmap must be clearly progressive and accurately indicating of their respective difficulties, excluding: - The highest difficulty of each game mode. - The highest difficulties of each game mode with a similar level of difficulty, applying only to Insane and Extra difficulties (e.g. the Insane difficulties of a ENHIIII set or the Extra difficulties of a ENHIIXXX set).
If we consider difficulty names consisting only of usernames, these are typically not fully descriptive of their difficulty levels, so the rule above applies for them as well (for example, "Skystar" would not be allowed as a difficulty name for an Hard if there already is an Insane difficulty in the set).
