NA friend by friend was much more successful than SEA strictly in terms of the rando situation, but i'm pretty sure that was just due purely to luck because there was no host there for most of the hours.
But there were still a decent chunk of randos it seems, as well as mamamad and it's braindead orbiters. I hope the map will have some automated anti-rando and security options for next year. It wasn't really that much of an issue the previous years but this time it was unacceptably bad in some timezones and some people were complaining last thread about NA getting slightly rando infested.
