Currently, I feel really restricted by the camera angles that Divinity Original Sin has (and the odd choice to restrict our rotation to 90° ) I see no reason in this game why that is the case. Surely you have made proper 3d models for this game, and so you could allow us a completely free camera rotation around our character pivot. Including pitch and height, no?
Unfortunately, no. The game has been designed from the very beginning as having a fixed view angle - so models lack textures etc. on sides which you can not see.
