Not really. Your argument makes no sense. In normal mode, people are actually notified when their friends are in trouble and are persuaded to help them. In realism, no one gives a flying fuck whether you're caught by smoker or getting pummeled by a charger.
Realism brings nothing to the table. It only takes things away. It's hard enough to find a game of competent players when they have the game telling them what to do. You're assuming that only good players play realism, which is not the case. You're just as likely to get into a game full of half brained two year olds as you would be in regular campaign mode, but now you don't have anything to help those half brained two year olds figure out that you're getting face fucked by a jockey while they wank off in the corner because they can't figure out what they should be doing.
