Battlefront on Hard

You know what really grinds my gears...Battlefront on Hard. The Medium difficulty is too easy to win but Hard is impossible. Even though you are on a team of like 30, you have to play babysitter for all of your command posts because no one stays behind to guard it and some prick gets a free steal. And of course, your team isn't smart enough to capture command posts on your own so there's no way to win. But what I really hate is when you don't die, lose all command posts but yet still lose. I never died so they obviously didn't kill everyone. Yet somehow we lose. I'm not sure why I keep playing it but it drives me nuts!
