I was sure there was a discussion about this somewhere, but I couldn't find it :<
However, it has resulted in modders telling people to remove a difficulty to bring it in line with the rule. Removing a difficulty will never improve the spread of a mapset - it's just a waste of a mapper's work.
Another example - an E N H I I I mapset. Assuming all of the easier difficulties are well constructed, where is the issue here? And how does removing one of the insanes improve the mapset in any way?
I say this rule should be removed in favour of rules that prevent large gaps in a spread - all spread related issues come as a result of too large a jump between different difficulties.
A mapset must not have more than two difficulties in the same difficulty level (not based on stars, but on how the map "feels"). That is, a map set can have no more than two "Insane" difficulties, etc, so that the diff spread is varied and balanced. Taiko-specific difficulties are an exception to this rule, but a good spread must be retained (e.g. two osu!standard Insanes, two Taiko Insanes, and one or two other difficulties is completely unbalanced and will not get ranked).The point of this rule was to prevent spreads such as E I I I, which is inappropriate as it doesn't cater to players of a skill level between easy and insane. What this rule hopes the mapper would do is tone one of the insanes down to a hard to make E H I I, which is obviously an improvement to the spread.
