@DrabMosquito312 Its not, I tested it by using 3rd party software to see if there is any packet loss. This is the server, this also happened back around 2015 on the Japanese server but it was fixed, for some reason...the NA server has the problem.
Okay, I've done this since JP release of E3 and now on NA E3, it is NOT Sega's servers and it wasn't then either. The difference is, I lived in Japan. I'm not saying the error doesn't exist, however..there's a SIGNIFICANT difference of people experiencing this from Japan and connecting outside of it.
The error first started being a problem after Sega blocked western connections to the JP servers. It was "fixed" in Jp version because the IP Region blocking was lifted and they allowed proper routing through the lobby and content servers.
If it's happening to you and select people with similar ISPs or through the same route/node/backbone..it's an ISP problem.
