I agree that when an enemy caster starts or ends their turn by casting a spell, the action has usually moved on by the time I’ve fully realized what they did to whom. For following attacks and movement, a zoomed out camera works best.
I haven’t really minded so far because there are no decisions to be made until your own turn, at which point there’s plenty of time to assess what happened and react accordingly.
However, if the next patch revamps reactions, the player will need to be able to fully understand what’s going on around them. Then the camera might be an issue.
