@StarMystro I've noticed it happening more and more when the last event came out. A lot of player's names are simply not loading. Sometimes my own teammate who I loaded into the match with, would have the unknown name. I know what their name is, but the "this is your squad" screen shows them as unknown, instead of the name used in the lobby. This isn't "streamer mode". Streamer mode only really affects people watching the player who's suppose to be streaming. AKA, if the player snipes someone it can say "Player3451 <kraber> Test321", and people won't know who Player3451 is, but as the person gets popular and find themselves being found by their fans, they would be able to hide "Test321's" name as well, as the people in the kill feed, so viewers won't know which "player" is their streamer. They also add in a few seconds of a delay to streams, so people can't just jump where they were.
This whole "Unknown" makes Z E R O sense to be "Streamers", since it's more like "which "unknown" is who", and also the fact that they usually load in when reporting on origin or when you open the death tab a few times.
