You NEVER press move backwards EVER unless you are positioning as a tank, you only strafe or mouse turn. 1st step in keybinding is to unbind left/right turn and backpedal. AND no this is not even a preference, this is basic movement that should be default, i dont even care if someone is a clicker or not, but this is how you should move. Your guild or ANY WoW 101 guide should have thought you this 15 years ago.
