Why can't we use the same camera controls that Sims 3 uses? I mean, it's certainly what *I'm* used to, and considering that any given expansion pack for Sims 2 or Sims 3 probably sold more individual copies than everything in the entire Total War franchise, these camera controls would certainly be more popular and would have a lot more people who are used to them.
Holding down the right mouse button allows you to move the location of the camera while looking in the same direction. Holding down the middle mouse button allows you to rotate the camera around the current viewpoint and raise and lower it. Moving the mouse wheel allows you to zoom in and out.
There is an options setting that allows edge scrolling to be turned on or off. Since most of the mouse action will be away from the edges of the screen, accidentally moving the camera doesn't happen often. If you had to use the mouse at the edges of the screen, this would be a problem.
Left clicking on a Sim's portrait in the list (or for HWLG a unit in the unit list) will select that Sim, left click again and the camera centers on it. Right clicking on the portrait will both select and lock the camera on the Sim (like the F6 key does in HWLG).
Pressing the TAB key toggles "cameraman" mode where moving the mouse looks around and you move the camera and raise and lower it with the keyboard. This is very useful for movie making. There was a "headbone" cam view (similar to the F5 view in HWLG) in pre-release versions of Sims 2 where the camera was attached to the head of the selected Sim and followed their movements, and you could look around by moving the mouse, but that was removed before release.
Of course, some of these would need to be optimized because the needs of HWLG are different from the needs of Sims 3. It does have the advantage that everything done with the camera during normal play is handled by the mouse.

I don't expect any of this to be implemented, but it illustrates an alternate viewpoint. However, there is one thing I'd like to see in HWLG eventually:
The speed of camera movement or rotation is controlled by how far the mouse is moved from the spot where the center or right button is clicked rather than from the center of the screen. This gives the movement a more natural feel and you don't have to keep track of where the mouse is before you press one of the buttons.
