I've been having a problem using the Energy Sword on Halo 3. Usually, 1 swipe is all it takes to kill an opponent. However, it seems that every time I lash at an opponent, they counter. How is this possible? It took 4 slashes last night to gain a kill on slayer using swords. I try to juke to the right or left when we're countering each other, but I just can't seem to do it.
