I guess we all have seen or experienced this situation. You were downed during a horde because of whatever and a teammate helps you get up again, so you get a small sequence where you see your character getting up in third-person mode and in exactly that moment, you get hit by several enemys, which causes your death without you being able to do anything.
Something like this shouldnt be in the game, because of the fact that one cant do anything in that moment. It should at least be possible to block during the sequence.
