Back during season of arrivals, I'd get an error maybe once a week. Then beyond light, it was once or twice a day. Bungie "streamlined" Destinys' net code, and it was once an hour by season 13. Season 14 and It's to the point where rejoining players from previous session has become a way of life. I just played Halo 5 Warzone, for the last 2 hours, with nothing short of a flawless connection. It's always just been Destiny that gives me the "check network settings". Any mmo, first person shooter, third person multi-player, driving Sim, or arcade style fighter, sees my connection and runs flawless. My nat is open, and I'm running a Xbox One X.
