So the recent locked camera discussion had me thinking about what I like and dislike about the camera function. The thing that bothers me most is having to continually flick my mouse to the edge of the screen during teamfights to make small adjustments to my view. This eats up time, concentration and accuracy during the middle of the most hectic portions of the game.
The solution: A new key-bindable function called Lock Camera to Mouse. Say you bind it to the spacebar (I would). While you hold down the spacebar, your camera moves in direct proportion to your mouse movement - without having to move the mouse to the edge of the screen.
Picture it this way. We have two champs roughly half a screen width apart - Teemo and Mundo. The camera is centered on Mundo, and you want to center it on Teemo instead.
T__________M
Old system: You move your mouse to the left edge of the screen, wait until the screen scrolls far enough to center on Teemo. You then move your mouse back to the center of the screen to click on useful things.
New system: You press and hold "Lock Camera to Mouse". You move your mouse the distance between Mundo and Teemo. You release "Lock Camera to Mouse".
During this time, your mouse remains in the same position relative to the camera. If it was dead center at the beginning, it will still be dead center at the end.
This is faster, because it involves much less movement and can be done as fast as you move your mouse. It is more accurate, because it operates on a 1 to 1 analog to your mouse movement. It requires less of your concentration, because with practice it can be done on instinct.
