Hi,
I thought I was state this as an annoyance with the camera control. Normally if you're traversing the 3D environment the camera zooms in when needing to avoid blocking an object in between you and the camera.
For the most part, this works really well. However, in some situations like in boss fights where having your camera at max distance becomes very useful, it can be inconvenient to say the least when you move in front of the temporary wall that's put up to lock you into the fight. The wall I'm referring to is the purple/violet translucent one that's put up after starting a boss encounter.
Here's a demonstration of the camera zooming in (6m 42s) :

The result is that some areas of the battle field give a good view point whilst others make it a lot tougher to observe the arena. The wall would not be in the way of the character at max distance.
