Currently there is a magnifying class on the minimap when in Haven. It's hotkey is = for me (I think it is default). If you press it, it zooms the camera in like it does when you're at the Auction House.
I'm not sure how different battle would be, or how annoying/harder, but would you want the option to be able to zoom in during battle?
I think it'd be neat to try out and immerse. Don't like, no big deal.
Thoughts?
