When you switch to free-aim it remains drag-scroll to control the cross-hair on screen, surely it should switch to WASD controls once in free-aim, ideally?
Also, the drag-scroll directions when aiming are inverted, not what you would expect.
No, not really. Controlling aim with keyboard and not the mouse doesn’t make much sense.
As for why it is drag and not freeaim, keep in mind: you might have more than one target to pick so players who are not that much into hotkeys would have to click on the “available enemy” buttons to switch targets quickly.
