Did you stick around? I'm curious if you could tell anything was up during game play.
edited to fix spelling errors.
I actually dropped into the dude's Collectors/Jade gip. It was kind of laggy and buggy as hell, I couldn't see the host, couldn't see collector nets, couldn't take cover and couldn't interact with the environment (revive, start objectives etc..) But it was my last game before heading to work so I decided to suck it up and keep going.
The game itself was very mediocre. We extracted in 21 something minutes, which isn't that good but isn't bad either, so I wouldn't say it affected gameplay. If he actually had a rank 255 gun, the game would have gone much faster.
I only noticed the Valiant 255 when we were in lobby. I tried asking how he did that but got no response back, because.. you know.. Pc mute race.
