Movement in WoW is a big thing! Imagine running away from a huge group of Alliance that is running towards you. Maybe your first instinct would be to use the s-key, which moves your character backwards. Or then again, a better answer might be to use the "a" or "d" keys to turn around, and then use the "w" key to run away. Both would work if you were trying to get away, but they are not the best answer!
So what is the best answer? How do we get away from enemy players or mobs that are trying to harm us without backpedaling slowly using the s-key? Or how can we turn faster than using the "a" or "d" keys? The answer is very simple!..
