I want to suggest that a new set of default controls for moving and shooting be selected.
Reading posts from various people on the forum indicates that people do get stuck in the middle of fights. Just watching other people when playing shows that sitting and firing is common.
Running away while firing isn't easy with the default setup. Yes, "click to move" is simple. But if people learn "click to move", then trying to aim and fire while backing up is hard. There is no default setting for "Move backwards", and I'm not sure what a good setting would be.
There is also the issue of left/right handidness. WASD by default will move without changing facing, so for right handed mouse users, with a two button mouse, keyboard moving and mouse aiming works. But that's not documented anywhere I can find; you either stumble on it by looking over the controls, or reading the forums. And it doesn't work for left handed mouse users, one button mouse users, or trackpad users (my experience, anyways).
A simple "Left or right handed?" question, and reversing the WASD and arrows, and mouse buttons, would be a good start. But then the fixed text in the tutorial is off, and if your left hand is on the mouse to aim, and your right hand is on the arrows to move, no finger is near X to defend, so it needs a new location as well.
I set up my movement to WASD and shield to right click with left click to shoot. Whatever the default set-up was is horrible and definitely at the very least needs to be reconsidered.
