It's easy to make most games look good in a video. Those were great clips, but you would have to play 80 games just to get a 2 minute video. I'm not complaining about this fact, but BF3 takes almost all the "luck" out of the game. You are either good or not. If you aren't, you will almost never have anything happen (action wise) that was in those clips.
In QL you can be a complete nub and still hit an amazing rocket, by luck. In CoD you can get a lucky across the map tomahawk or knife throw. In BF3, to get kills, you better know how to play.
