I think that we should add a waiting period of 12 hours between bubbling and qualifying a map based on what I have seen and experienced as a taiko modder (that I assume applies to other modes, which is why I'm making this general). This may seem inconvenient and pointless at face value, but I assure you that the reasons for this change are great enough to justify the minor inconvenience it would pose to nominators.
The current state of ranking
Currently, if a map has 2 BNs that agree to nominate it, bubbling practically doesn't exist as the BNs will typically nominate very close to one another, sometimes even instantly (within a few minutes of each other). This isn't just an assumption, you can go through the most recent ranked maps and look at the gaps between bubble and qualification for yourself. As of writing this, (April 10th, 11:41 AM PST), the 10 most recent ranked maps in all modes have gaps of 7 minutes, 11 minutes, 8 minutes, 2 minutes, 69 minutes, 10 hours (the first qualification was literally the same minute, though), 22 hours (after being popped once previously), 10 minutes, 3 minutes, and 7 hours.
Obviously, the majority of maps are currently under this 12 hour gap I propose, and therefore are, in my opinion, not letting enough time for people to notice the map and mod it while it is bubbled. Since the entire point of bubbling a map is to bring it to the attention of other modders, this practice of instantly qualifying maps is making the two-step process completely pointless and therefore detracting from the overall quality of maps in the ranked section.
Why this is bad practice
While this is a positive for the BNs as it simplifies the ranking process, I believe that the negatives this practice brings to map quality and making sure we are putting flawless maps into ranked every time far exceed the need for simplicity. One of these negatives is that there are issues that maps can have that are not technically unrankable, but should be fixed, and are only worth being fixed (to mappers and BNs) if the map is either not nominated or in bubble state. Otherwise, any of these issues that are pointed out while a map is qualified will most likely be argued against on the terms of "technically not unrankable," which, in my opinion, is a lazy excuse to use against a legitimate and good suggestion, and is no way to be putting maps into the ranked section where they will never be changed.
The most prominent example of issues that are like this is tag issues, such as adding missing tags or removingduplicated or unnecessary tags. This is something that has been contentious in the past, with some maps being disqualified due to having tags that misrepresent the music, and other maps with duplicate tags being waved into ranked with BNs giving the excuse of "nothing technically unrankable about duplicated tags." This is currently acceptable, but I believe it would be avoidable if people didn't qualify maps within 2 minutes of nominating them. I have been notified there is nothing in the RC stating anything about duplicate tags. A similar issue that typically is only addressed while a map is bubbled is audio quality. If someone gives a mapper better quality audio than they are using while their map is qualified, the chances are they will not take it as it isn't unrankable to rank a map with poorer audio quality than what is available. Basically, all of the guidelines in the RC are treated this way, but since BNs aren't letting maps be bubbled for a decent amount of time, any map that breaks the guidelines most likely will not fix something that is pointed out while in qualification, as it is up to the mapper whether to disqualify their map or not. This includes issues such as inconsistent or incorrect kiai usage, enable countdown inconsistencies, guidelines regarding guest difficulty naming, poor quality backgrounds, certain metadata issues, and other issues that can contribute to an overall sub-optimal player experience.
The purpose of the bubbled state
Another thing that the bubbled state is for that I already briefly mentioned earlier is bringing a map to the attention of the general modding community. If a BN missed anything on their first pass, then the community can pick up on it and fix it easily while the map is in a bubbled state. However, with the way maps are being ranked, that is impossible. Now, if attention is brought to a map to the general modding community, it is in a state where both the mapper and BNs are very reluctant to reset the nomination process. Basically, any subjective issues can be ignored, and, as I mentioned before, fringe-unrankable issues or unnecessary guideline breaches can also be practically ignored since they aren't strictly unrankable, even if they would genuinely increase the quality of the map or if there is no legitimate reason why the change should not be made.
Now, you may say to yourself, "but the purpose of a second BN is to make sure that the first BN did not miss anything. If a second BN nominates it, then the map didn't need further modding." And that is where I'm just going to have to disagree. I have seen several maps just within the past week that could have been modded better, even with very simple things such as finisher inconsistencies, and very often these second nominators leave very few points, if any at all, and I doubt I am the only person to have caught these kinds of problems in qualified maps. Most people, however, will not even bother leaving points on qualified maps because it's quite futile to expect a mapper to willingly disqualify for a subjective or technically unnecessary change. In the case of my example with the finisher inconsistencies, the second nominator did not leave a single suggestion on the map. This isn't meant to say that the second nominator is bad, I'm saying that I think it would be better if people had the opportunity to mod a map while it was bubbled so that mappers and BNs would be more open to these kinds of changes.
Reasoning for the length
So why 12 hours? Because we used to have 24 hours and everybody hated it, 8 hours is too difficult to remember, and I think 6 hours is way too short. If you consider a (very) active modder's everyday life, they probably work about 8 hours, sleep about 8 hours, and sometime between those two, go on osu! to check out maps and play the game. While I am aware there is more than one modder in the game, I'm basing this off of a single person's life because it's simple and easy to explain, and also because in some modes there really are only a few people who are willing to check bubbled/qualified maps. A 6 hour period would allow for someone to go to sleep and wake up and see a map they have never seen before in the qualified state, meaning they were denied even the possibility of modding it. A period of 12 hours allows BNs to take a map from nothing to qualification within the same day while still allowing a decent period of time for people with average lives to be able to have the opportunity to check the map while it is bubbled.
Negatives and other considerations
And what about the drawbacks of this proposal? I honestly cannot think of many, I would appreciate it if someone could think of some reason why there shouldn't be a mandatory time period between bubbling and qualification. The only thing I can possibly come up with is that it's kind of inconvenient if 2 BNs are checking a map at the same time for one to wait 12 hours before qualifying it, but that is not enough of an excuse considering all of the positive effects I've explained here and, from a former BN's perspective, is something I would be willing to do for the sake of general ranking quality. Another very small thing would be that it takes half a day longer for a map to go from pending to ranked, but given that there are maps that have been sitting in bubble for literally months, I don't see that as much of an issue, and obviously the BNG doesn't think so either if they are willing to let several maps sit in bubbled state for so long (the most prominent of which being this map that was nominated on August 9th, 2020).
One consideration is multi-mode sets, which I kind of already addressed in the title. I specify first and last instead of first and second because I think that this period should apply equally to every set. It would ridiculous for a 4-mode set to have to wait 84 hours to enter qualification (7 wait periods of 12 hours).
I would also like to add that this waiting period would apply to every instance of the nomination process. If a map is disqualified, they shouldn't be able to bypass this restriction as a disqualification does not guarantee that all of the issues, subjective and unrankable, have been addressed. This point is highly open to discussion, I would be willing to allow a shorter period since it is true that disqualification puts a map in a spotlight and typically fixes most of the issues the map has, so maybe 6 hours would be acceptable, but for now I'm going to say that the 12 hour period should apply. This might have a drawback of people being even more reluctant to disqualify maps, however, people are already incredibly reluctant to disqualify maps as we are, so I don't think it would make much of a difference.
The same discussion that applies to the disqualification thing might not apply to a map being reset from its bubbled state as this might make maps open to abuse from modders with bad intentions. My proposal for this would be that the timer doesn't reset on a bubble reset similar to how the ranking timer does not reset when a map is disqualified, so if a map is modded 6 hours after it is nominated and it is reset, when it is bubbled again, the timer will start at 6 hours instead of restarting. Although I would prefer for the 12 hour period to be applied on every nomination, I think it's also important to take into consideration other possibilities.
