Strafing is a techinical word for jumping while running. It allows players to be quicker than the others. Strafing uses the W key as well as the A and D key, sometimes all pressed at once. Strafing is commonly a sign for high leveled opponents, and the faster they go, the more experienced they are. Strafing is considered to be an important art in Uberstrike.
Strafing makes it easier to get from one place to another quicker eg. Cuberstrike . It also makes it harder to kill you, since your not a sitting duck. It makes it harder for people since they have to constantly re-aim to shoot you, and since you move quicker, you can kill them easier too.
It puts strain into your hands. And Its dangerous. And thats it!
