As a related issue, currently, when the camera is locked, the spacebar does nothing.
As someone who spends >90% of the game with the spacebar held down, I feel like it would be an improvement to allow people to hold space to unlock their camera if they're in locked mode. Releasing the spacebar would snap the camera back to the player.
This would allow a quick temporary switch in order to line up a skill shot, while leaving general gameplay unchanged.
As mentioned earlier, the pros that seem to play with locked cameras tend to actually hold down spacebar. This adjustment allows for an essentially identical play style with somewhat more ergonomic input.
