They wanted to make it realistic? Well they failed.
Here's an example - 50 cal sniper rifle bullet will tear a human apart, however in this game (which was supposed to be realistic) the guy survives and then heals... This along with shooting a shotgun from fucking 100 meters and driving a tank on a cliff and spamming it...
However the major fail is it's bugs/glitches/compatibility issues. I can't even play the game for 5 minutes without crashing/freezing/hard, sound looping (my PC specs are fantastic though, 16 cores and e.t.c. Windows 7 user), along with a shitload of other people and EA is not only not doing shit about it, but it even releases patches saying that "they've fixed all the major problems"...
