Can you rotate or otherwise change your viewpoint in Diablo 3?
The title says it all. Stuff's in my way. I can't see. Can I fix this?
No. Diablo history is the main reason why.

You cannot rotate the view but you can change it a little bit by pressing the Z key (or whatever you bound to Toggle Zoom).
