Vel'Koz Ult Aiming (Quality of Life)

Just a thought on a quality-of-life buff for Vel'Koz. Can his ult be changed so that the camera is locked on your mouse cursor, basically like Sion's ult? I say this because Vel'Koz's ult does reach off-screen, and moving the camera would result in your cursor being displaced from it's original position relative to the map (i.e. moving your camera up would result in your cursor moving up as well) so you have to move the camera before ulting, and even a split second (maybe longer, depending on your camera scroll speed) can make a difference in League. Not only that, but your own champion would then possibly be off-screen, making you even more vulnerable than Vel'Koz already is.
