In short:
We need key bindings for sidestep right/ sidestep left without a stance key.
Sidestep is as important as lean and should not be discriminated by stance adjustment-system.
Adjustment upwards and downwards should be controlled by scrollwheel and free adjustment key.

In long:
During alpha and beta phase the stance adjustments - well, more precisely: the stance animations - have been improved continuously. For sure, there is still some work to do. But it becomes more and more clear, that we need another access to the stance animations.

At the moment, we have an electable adjust-stance-key, here it is "Ctrl". Vertical stance adjustment is done by Ctrl+W and Ctrl+S, horizontal adjustment is done by Ctrl+A and Ctrl+D. Additionally we can lean sideways with E and Q (either for short or for "toggle").

The problems with this system explained by example:
1.)
You are in stationary position, taking cover behind a houses edge with sidestep right - all is fine.
2.)
You want to change your position rapidly. You move (or sprint) 5 or 10 meters to the other location.
3.)
At your destination you have to adjust your stance to sidestep left.
4.)
As you were moving, you could already see that you will have to (or want to) change your stance. Unfortunately you couldn't adjust your stance on the move.

Second problem correlating to stance adjustment:
1.)
I personally use (precisely: would like to use) "sidestep right" more often then "lean right".
2.)
I use lean options only in toggle on/off mode.
3.)
Now imagine: If you sidestep right (Ctrl+D) and lean right stationary (E) - all is fine.
4.)
If you have to change your position and thereafter your stance, you get extremely in trouble, because you have to use stance-key (Ctrl), direction-key (A), and lean-key (E or Q).
5.)

Case 1

To get from lean right (pushed E) to normal stance, you have to press E (same key, same direction).
To get from sidestep right (pushed Ctrl+D) to normal stance, you have to press Ctrl+A (opposite direction).
6.)

Case 2

To get from lean right (pushed E) to lean left, you have to press Q (opposite direction).
To get from sidestep right (pushed Ctrl+D) to sidestep left, you have to press Ctrl+A plus Ctrl+A (opposite direction times two).
7.)

Case 3

To get from [sidestep right, lean right] to [sidestep left, no lean], you have to press E (same direction) and Ctrl+A plus Ctrl+A (2x opposite direction).

The stance adjustment is a big improvement. Unfortunately the body control is contrarotating and the stance key prevents from adjustments on the move.

What we need is to access to sidestep right/ sidestep left without a stance key. Additionally the vertical stance adjustment cannot be done on the move, too. Therefore the vertical adjustment should be handled by scrollwheel+"adjustment key".

Thanks for your attention.
