It would make the beta much more playable if we knew where battles are taking place. it is difficult at best when more than 2 hours into a game to know where a fight might take place. At one point I lost a shipyard in the middle of 3 planets that was building my transports and I didnt even notice because I had 1 gap in my sensor line. I finally noticed when I didnt get a transport when I was supposed to.
Now that being said I could actually see some sort of a way to use this. Such as a HUGE Galactic event that shuts down all long range communications. That way any battles would not be shown to the player and all trade with other civs is shut down for the time.
