Yeah i understand you, but as long as you know that the door could kill you : Don´t stand/Crouch/prone there !
The door Kick-breaching has been integrated by the developers as a new feature and i think they will not take it out just because some players don´t like the one-hit-kill of the door.
I doubt that they even will change the door-kill just into a temporary blurred vision effect or something like that.
So, just avoid the area in front of doors
They can remove death by door and keep the cool kick the door in feature.
What is missing from the discussion, from what I have seen, is the situation where two players both go for kicking down the same door. The one who press the key first is the victor, which seem highly undeserved. This is a major issue game theory wise.
