It would be boring to start every battle with the default game camera. The Youtube trailer have different camera angles, very cinematic (like this at 01:00, https://youtu.be/bTWTFX8qzPI?t=60 ). It would be cool to have some cinematic shots/views before starting some of the battles.
I really like in X-Com 2 (or even Final Fantasy 7,8,9,X) when someone's turn is up, the camera cuts to them, and they do their attack. Every time I do a battle in DOS I wish there was something similar.
