Doesn’t Nintendo use people’s Internet themselves? Like one of the players Switches becomes the host and how well the connection is is based on the host’s (and the other players) Internet?
I ended up spending a few days researching about this. You would be correct that the person who's the first one to open a session (AKA joining matchmaking round) would be the host and the rest would be "clients". However, there are also plenty of times where I "host" a private battle or Grizzco job, yet I sometimes get unstable connections or get kicked out. And I know I have excellent internet connection. So I'm not sure what the deal was there...
@@Princess_I At least getting kicked out is better than losing because of the connection. I got an unstable Internet connecting a few days ago in Salmon Run, Chum hit me right under a Slammin’ Lid while I was unable to move at all. It happened just as the last person died or disconnected too.
