There is a precedent of a similar case being ranked https://osu.ppy.sh/s/189756 , but a little unsure since there are taiko diffs here.
Personally I think it should be fine, but I'd like to get opinions from the team to be sure.
No guest mapper should have more difficulties in the mapset than the creator, all modes together. For collaboration mapsets, the uploader should take part in all collab difficulties. The person who should upload the map is the one who contributed most to it. Maps with an ambiguous set of difficulties such as collabs will be evaluated on a case-by-case basis to ensure that the submitting mapper is properly accounted for.
So a little concern for this mapset since 4 standard difficulties are all collaborated, and there are 2 taiko difficulties mapped by one mapper.There is a precedent of a similar case being ranked https://osu.ppy.sh/s/189756 , but a little unsure since there are taiko diffs here.
