Thanks for the suggestion Rongway.

I should have clarified the specific issues I had with the camera with Legacy controls.

With Standard controls, "Left Click + Mouse" controls the camera without affecting the characters facing direction, and "Right Click + Mouse" does this + affects the characters facing direction.
"Left Click + Mouse" = Only camera movement, while the character is standing still.
"Left Click + Mouse" = Only camera movement, while the character is moving.
"Right Click + Mouse" = Also affects character facing, while the character is standing still.
"Right Click + Mouse" = Also affects character facing, while the character is moving.

With Legacy controls, Left Click and Right Click have the exact same functionality, and change based on character movement.
"Left Click + Mouse" or "Right Click + Mouse" = Only camera movement, while the character is standing still.
"Left Click + Mouse" or "Right Click + Mouse" = Also affects character facing, while the character is moving.

Looking above, I lose functionality of 2 of the previous camera / character controls I previously had with standard movement. It is also just confusing to try and learn and relearn this different type of character/camera movement, especially when I switch between other games that don't use this kind of camera movement.
