I am terrible at this game, and I used a naturally gimped weapon, so I have to be crafty in order to kill people. I find that the most effective method is the stare down, when you are fighting two people just keep the second guy peripheral vision and use footwork to keep a safe distance, when you see an opening, stab at the guy you arent looking at directly, 2-4 times you can catch him mid swing. Since I suck so bad, I bore my opponents to death, backpedal kick stab run away repeat.
