When grabbing the camera to strafe/kite with RMB, hiding your mouse can make it a little harder to use ground targeted skills such as Thief Clusterbomb, Necro Marks, Engy Nades, my suggestion would be to allow an option to show your Mouse as a reticle when holding down the RMB to grab your camera.
This would make it alot easier to see where you’re aiming while kiting/strafing with your mouse.
