This is a team game, and while other games focus on what you're doing, you need to be able to see as much as you can at the same time. While the map helps with this, it doesn't give you the feel of proximity to what's going on nearby you, or, away from you. Let's say you're mid, you run down mid, and stand at your outer tower. The fog of war isn't changing based on where your mouse or camera is, but rather a range of view relative to your champion's location and which direction they're facing, at what object. It took me a week or so to get used to the unlocked camera, but almost IMMEDIATELY, I saw positive changes in my playstyle, habits, decision-making, positioning, etc. If you want the camera to center on you temporarily while it's unlocked, you can always press the Spacebar. That comes in handy during teamfights.
