You can map up to 6 difficulties in a mapset per game mode. The lowest difficulty of your set must be below 2*. All difficulties must be evenly spread apart and offer a linear progression. However, you can add a bonus difficulty. For that, the highest difficulty of your evenly spread set must be above 5.25*. The bonus difficulty does not have to align with the rest of the mapset's spread, but must be hardest of the entire mapset. You must not have more than 2 difficulties of the same level in your mapset per game mode. Approval maps are allowed to have only one difficuty if they're not Expert level. If it does, it needs an additional difficulty of Insane or Hard level. Maps over 10 minutes of drain time do not account for this rule and can have a single difficulty of any level.

Assisting ztrot's proposal to move it into the desired path here. If you have questions or concerns about this, you are free to contact him about it.Given the misconceptions of the way the original amendment was worded, we came up with a better regulation, that reflects the intended change in a better way without implying more "restrictive behavior" than actually wanted.Along with that, we attempted to improve the free form of designing your spread a bit, while maintaining the basic idea behind the changes proposed.This basically allows multiple constellations of mapsets, given that every individual difficulty is spread apart from each other in a linear way. For example:(where U refers to Ultra, now referred as bonus difficulty in the rules)ENHIIX + U is fineENHHIX + U is fineENHIX + U is fineNHIX + U is fineNHIXX + U is fineNHIIXX + U is fineNHIXX is fineENHIX is fineNNHII is fineENHHII is fineNHIXXX + U is not fine (cant be more than 2 X)NNHHIIXX + U is not fine (exceeds the cap of 6+1)ENHHIII is not fine (exceeds the cap of 6 and can't have 3 I)For approval, this would mean(>5:00 but <10:00 drain time)E is fineN is fineH is fineI is fineX is not fine (it's an Expert, must have an Insane or Hard, too)HX is fineIX is fineXX is not fine (still has no Insane or Hard)IXX is fineetc.(>10:00 drain time)every kind of single difficulty is allowed. The level doesn't matter.We were torn in the Approval rule between allowing only IX or also HX. Maybe you guys have input for that matter, as well. We allowed both in the new proposal, but moving on with the feedback we gather from this thread and other places, we might find it easier to make a decision with that.Additionally, ztrot reconsidered our transistion method to the new behavior. Instead of allowing beatmaps, that have been bubbled at some point of time, to be excluded from the rule change, we expand this allowance to all beatmaps that are currently submitted. This means, all beatmaps uploaded right now can be ranked under the old conditions, still. Newly submitted beatmaps must follow the new regulations, whenever they kick in. However, after, all beatmaps will be handled under the new conditions, regardless of their submission date.For now, the topic remains locked until peppy decides to unlock it again. I am just informing everyone that there is active efforts to adjust the proposal to both ends of the needs.
