Can we please take a look at how Semi-Locked camera works?
I love the idea of semi-locked camera, it's really nice to have a following camera that one can reposition to better match the situation.
The only major flaw with it currently is there is no way to re-set it back to center without manually trying to shift back to center.
Let's take a look at how the default camera works in Heroes of the Storm.
If you have it unlocked, and you hold down spacebar it will center the camera. You can also move it around just like in Semi-Locked, but the main difference is when you press spacebar again it will re-center your camera.
This for me, and I'm sure the majority of people who would like to use semi-locked prefer this.
I'm requesting that either the camera reset's upon re-lock or you add a separate keybind to reset it to the middle.
EDIT: I'm going to make a little video showing the issue and what it should be like.
