I use legacy settings (in the character configuration menu: I also have 3rd person camera checked for mouse/keyboard and gamepad). I play with a controller in my left hand to control movement, and a mouse in my right hand for everything else. I adjust the camera angle with the mouse in my right hand by clicking on the screen in the direction I want to view. I can zoom in and out with the wheel of the mouse. I usually hold the controller on my lap (although sometimes I set it on the desk as well) when I sit at the computer.
