Happened to me today during a solo UG run Phase 3 LMG Riker boss and his shotgunner buddy dropped me like bag of bricks . Survival didn ' t proc . I got sad after that . My guess is that , programmatically speaking , there is a pool of health in which the ' downed state ' resides , and Survival Link only procs when you enter that specific pool by taking some required amount if damage . The theory part is that if you take enough damage to go beyond that ' downed state ' you see it happen in the DZ every now and then with MMR headshots , then SL won ' t pop . That , or , I ' m totally offbase and it ' s bugged under certain asyet unidentied conditions . I ' m gonna give the devs the benefit of the doubt . <| sep |> Yeah , the traffic was insane . 6070 people trying at the same time . Graham ' s working at it .
