You're still making no sense at all, as you're applying real life consequences to a video game where you can survive an entire clip from an auto rifle. It's pretty obvious all games have some hint of realism, as all stories have morals you can apply to real life and the fact that characters are humans, but none would ever fathom to take into detail tht you're going through. It's a weak counter argument and should be revised. It's as simply as that. A sniper shouldn't be able to kill overshield players, as the mechanic of the overshield is to prevent Rez camping and allow players another chance.
