You can watch a fighting video 1000 times, and then go and try to fight a professional boxer who has experienced it first hand, guess what will happen^^
Though watching a vid may help you understand the mechanics, god help you when things don't go like just in the video... which they never do
Should help players learn to adapt to changing situations in game, ie, letting them experience it and not rag about how they've come to play the game unprepared lol not to go study a vid which the game rarely plays out in DF groups anyways imo.
