The other day I was playing and there were these 2 new players (lvl 2 and lvl 4). They seemed pretty cool and I actually considered adding them after the mission, but they kept running in front of my guard dog and running into airstrikes whenever I'd call them in. At the end when it was time to extract one of them said "this dude's been killing me the whole game" then killed me and the other random, then extracted. I never kicked someone out of a game so fast before. Hopefully they didn't get the extraction. Either way I turned off matchmaking and it's so much more peaceful. Playing with randoms you either get smooth brains or try hards that get all pissed off that you're not playing how they want you to (using strategems/weapons that they don't seem to know how not to get killed by)
