This logic does make a lot of sense especially when the map pool becomes huge
Still, its tough for a veteran player to sympathize that hard with new players, and most players here likely play more than the majority of the playerbase. Swiftplay seems like the best onboarding mode, and probably some of the best warmup modes as well, so I would agree with the decision to move it to the regular pool. However, and this may just be my individual opinion, it would be really nice if atleast spikerush kept the full pool, allowing it to lean further into its wacky and relaxed theme.
I think this is a reasonable take fwiw, it's something we've talked about. We just wanted to try the universal consistent approach first to see how it went.
