I would equate most player success is not emulating what majority are doing. Except for the obvious noobish mistakes a few games can help you get the gist of how people move beginning to end of the game. Players that last long have a remarkably different play style. Is it just me or most of the top 10 behaviors of surviving the game long is not engaging in early skirmishes? I just casually observe this game being played by a friend to relate this far. I play a different FPS game and you're on point about choosing the right weapon to go with your play style.
