Since everyone is on an even playing field with the same system, it does indeed require skill. If the game was XCOM, where you told the game who you want to shoot and it calculates whether you hit them or not, then there would be no shooting skill involved. (There would still be strategic and tactical skill.) But there IS dexterity and hand-eye coordination involved in playing Destiny. That's why some people are better at it than others. You're fooling yourself to think this video "proves" anything to the contrary.
