I turn on semi locked camera so I can push the camera towards the action and have it stay offset from my champion (similar to the offset camera we have in league). I also use my index/2nd finger to navigate the camera on the minimap. It takes a bit of practice, but I don't find it jittery. Also useful for aiming long range ults, you can use the minimap to pan the camera and then when you aim your ult it happens within the camera view so it's more accurate than aiming without moving the camera across the map.
