In order to have a proper third person we need to have proper z axis movement. If they can fix this then I think an in game toggle to switch the controls would be great. WASD or equivalent for movement and mouse wheel to zoom in and out while in the third person (could also allow first person when zoomed in all the way,) and mouse to turn character and adjust sight angle would be ideal for me. We could then use the toggle to switch back to what we have now or some sort of tactical camera if it was needed.
