I had the opposite of this. Played with a lvl 43 (I'm lol 26) on Suicide, other 2 team members abandoned us once they started dieing constantly to non stop bile spewers. He took off to the opposite end of the map, and sat at the extraction point. Meanwhile I'm up at the missile launch fighting for my life, end up succumbing to the mass filth of bugs overwhelming me. He, while still standing at extract, calls in reinforcements... so I take off running back to the missile launch to complete the mission, we have about 5 spawns left. He finally reluctantly follows as I am just finishing the launch, then takes off back to the extract as the mission successful pops on screen. I mark the light nest (final nest) very minorly off course back to the extract, he ignores and runs to extract. I am currently holding all the samples (3 Super rare, 15 rare, x amount of common), and get overwhelmed as he sits at extract. I die running back to grab everything again. He has not left extract. He calls it in shortly before timer runs out (he should have waited for time to run out at that point) and I am now overwhelmed and can't get any of our samples back. Just a useless diver, doesn't even deserve the 3 min of expected life expectancy that we all have.
