The part I don't understand is how so many people use WASD. What a terrible contortion of your fingers! I used to play Q3 very heavily, and actually got cramps in my left hand from that key combination. Which is why I changed my bindings.
Take your left hand once again, flatten it out into a comfortable position, and let that lie on your keyboard. This is how I got the keys I now use - ERTZ. :>
