Okay. After consulting several BATs internally, the lack of hitsounds contradict with the general ranking criteria
General Ranking Criteria wrote:
You must use hitsounds. Without these, things get way too monotonous as you are throwing away one of the main elements of variation present in mapping. You don't need to place them on every note (and are discouraged from doing so), but they must at least be frequently heard when playing.
The general ranking criteria applies for all game modes, including mania.
Just because mania!BATs weren't aware so far, this doesn't provide any validity. Current mania responsible BATs will be set under knowledge that this kind of mapping is unwanted.
For the current state, the map is unrankable.
Please add hitsounds to your map. Then we can talk about a rerank.
Sorry.
If you want to object the existance of this persisting rule, please open a discussion thread in the ranking criteria subboards.
(Have I said that the map self is really awesome? Just saying)
