Fixed Camera Should Be Usable
I know this topic has been brought up many times, but I believe that since it has not been resolved it will continue to do come up until it has.
I believe that the estimates of the people that are affected by the fixed camera issues are low, this is due to the fact that people have quit League of Legends or don’t play often because locked camera is a poor way to play the game. This became extremely apparent when I was watching a quadriplegic gamer playing with locked camera. He said it was fun, but he couldn't see himself playing it regularly because of the camera. Unlocking his camera isn't an option. So if you are going to count how many people this affects you need to remember everyone, not just the people that play the game currently.
I understand the design choices of choosing to improve unlocked over improve locked, but the problem isn't with unlocked camera, many people find that mode of play practical. The problem is with locked camera, and it is because it is nearly unusable. The key would be to make unlocked camera usable, but not advantageous. I believe that this is possible with minimal effort and could not affect people that don’t need it.
The solution is this, it is as many people have suggested before, an adjustable camera offset, but with two suggestions from me. One it can only be turned on from the settings menu, and second it is adjusted by a modifying key and a click (This would work by setting the offset with respect to where your champion is compared to the click. In essence the camera would be centered on the click and camera would then stay that fixed distance from the champion.) This allows for on the fly adjustments of the camera, but allows for the camera to be tethered to the champions movement.
This solution isn't perfect, but training wheels are not supposed to be. This solution is so that people don’t quit playing league because they are not welcome.
