The tactical camera could use improvements. I hated it at first, then got used to it. I then went back and played Origins after beating Inquisition and the difference was like day and night. Origins was so much better.
But I will admit on thing. I found myself trying to use that invisible fifth party member that is the cursor view from DA:I, and I felt like Origins was missing something without it. I could still edge scroll, but I had to be zoomed out to do it. So that was a little frustrating.
I think the tactical view is okay, but it should be more like Origins, and it should keep the cursor scroll while also having edge scroll, and like others have posted it should not collide with the environment. I would add that objects should go transparent as well when zoomed out, just like Origins.
