No one here claimed that this stuff doesn't happen in a S-C environment, nor that S-C is the holy grail of networking. This is mostly a QoL issue. As others have already pointed out, relics networking is "meh", to put it carefully.
also, i don't know if you played on b.net back in the days
Yes, and I personally never had any problem with battle.net and that was back in the day when I still dialed in with a modem. Maybe I was excessively lucky or the people responsible at blizzard are just damn good at their job. Fact remains that I have trouble staying connected in relic games despite a uber 1337 h4x0r connection.
Since this hopefully won't be relics last game and they're the second worst at this network stuff right after Paradox Development Studio (who are literally stuck in 1989) I hope someone at relics snaps their fingers and hires a couple of guys to deal with it or something.
