So real warfare is only for casuals and noobs because people die with one bullet?
The real skill in hardcore shooters with a very fast time to kill is that:
“Rambo players”, that jump around, run through open field without cover, think they can tank a couple of shots to find out where the enemy is hiding win a firefight despite having already been hit a couple of times - all of that doesn’t work.
You shoot first and you win, no kiddos that play recklessly.
A forgiving damage model has always been the definition of a casual arcade shooter.
