An upheaval to me would require that the blatant favoritism amongst BNs is addressed. Quick bubbles are passed around as favors that will be returned in the future in some way or the other. I am not going to name people but public cases of this are well recorded and should be no surprise to anyone. I don't even want to know how bad this truly is when you are an insider that has access to these advantages.That may be true in the most part, but BNs are experienced mappers. We can't tell apart from what is made from connections and honest actions, I agree that we should also stop this from happening as it seems unfair with the majority of the mapping community. Monetary rewards such as supporter is enough for incentives.
The problem is that nominators are naturally mappers and have a lot of influence in the ranking process. This creates an obvious incentive for favoritism to help each other out with their own maps. When those who are in charge of running the system are actively participating in it as individuals themselves then there are going to be problems.
Connections are too big of a driver in the current ranking process. Those with access to the people in charge are highly advantaged compared to those that do not. When getting hold of a BN is incredibly frustrating for some, while others can simply post a short message in a private discord server to get things rolling quickly I do not consider it a fair system.
What this needs to be addressed is to make a rule (if this does so happen and if this will ever so happen) to prevent this from happening. Things such has "icon for icon" should be discouraged as it is unfair already as BNs/QATs already bypass what we regular members have to go through (for example the modding queues). Suspicious activity should be discouraged and even be punished by doing so.
Some BNs may choose to indirectly help a mapper because of favoritism while the mapper he so chooses to help doesn't know it. There should be a lock to prevent a specific BN iconing one mapper's maps. This can't fully stop but at least prevent the idea of speedranking in such a way too.
