High pacing and chaos is what looks cool in trailers and make for a great selling point from a commercial perspective. Everything has to be bigger, faster, more players, more weapons, more explosions,... People look at these trailers and are amazed. When the day actually arrives, they will buy the game, play it for a month or 2, get bored with it because there's no real addictive fun, it's superficial. Something new will arrive and player count will drop significant within months.
This is the BIGGEST mistake that is made over and over again with every battlefield game since battlefield 3. Gradually killing a once great franchise due to incompetent management with a superficial vision of what a good battlefield game is. They just don't get it...
