I used to be able to rotate my camera such that I was able to look at my own avatar and "puppeteer" him [arm movement etc].
Now when I attempt to switch the camera to FACE him it rotates the avatar so the camera is ALWAYS over the shoulder.
I think it is VITAL for Machinima and possibly other purposes to bring back this functionality of camera independence.
Could be a simple F key to decouple camera etc.
