On PC they definitely have a system in place that continually adapts the individual send and receive server and client tick rates according to client network quality. Maybe that's why they recommend no qos. I'm not sure they have the same system on console though. They said they were looking into it but then I read a post on the blizzard forums that seemed to imply it was already deployed. Ive had 2 ps4s on 70 70 and hyperlanes now for ages without any issues. I'll give it a shot without to see. Though its hard to tell when things go wrong in Overwatch due to the nature of the game. Every death always feels unfair especially those roadhog hooks or spamzo headshots....
