To add clarification to the OP's request I would like to specify, what is being asked:


He is stating, that specifically, when you move your character to the left or right only, the character performs a sort of a "circle", and the camera follows your character. Thus this "rotating camera" action.

I believe, he wants to move directly left, or right, as with "Standard" setting, but without the character forcing his face straight, and taking side steps as they do with standard setting.


Basically a full complete "character" and "camera" separation. This way you could essentially see a character running/moving naturally forward, from a side angle. Which is not possible with Standard, nor Legacy settings.
