Rank matching needs to be fundamentally revised.

Competitive games where ranked matches are not interesting will go out of business.
Ranked matches need to be as fair as possible. If the matching, which is the root of the game, is unbalanced, it is not worth talking about.
People often say that if you put restrictions on partying, they cannot play with friends and family, but I think such people should play casual games, not ranked ones.
As for ranked parties, I think it’s fine to limit CSRs to 300 or less. In fact, there are too many Onyx and Gold etc. parties and it is a hotbed of imbalance.
I think we should then balance that with matching times and match as close as possible to the CSRs.
