So, the current setting at the moment is hold Alt and move the mouse to change your camera angle, and I cant seem to grasp this concept being from a background of MMORPG's and such. I am accustomed to using the mouse to control my camera/view at all times. Why not have the free camera movment set as Mouse Button 3 "Wheel click" so that you can press and hold, adjust the camera and have Alt to return to default camera position. I think that would feel more comfortable to players who are used to controlling the camera from the mouse instead of having to utilize another key during battle along with the other 100 keys like with manual firing.
