Give me a break, dude. If you do not want to shoot at things that shoot back, I suggest offline.
It's reducing tactics and options. And by that I don't mean the ole "hiding to make a base flash for 2 hours".
When attacking a base, most players used to come in directly from the spawn. Better, or more 'creative' players chose to divert and search for alternate approaches. Smart opponents on the other side may suspect and try to counter such moves by searching in other likely places. With the current quadrant, it's almost pointless. Now it will be all about speed and time, because you are so easy to locate without even looking.
When facing an overwhelming assault, a lone defender in a tank could try to use shoot and scoot tactics. Ambush, then relocate quickly. Now, that won't really work anymore unless they willfully ignore their GV dar. They know you are there, and they can quickly triangulate your position long before they come into firing range, even when you are shut down and completely out of sight. Better sit in a place with the best armor you can afford, because flanking the enemy units on the move is not an option if they can see the quadrant moving.
When the horde had just captured a base, sometimes some bold guys were able to grab bag the base from under their butts with a tank and a m3, while the horde lifted for the next target in line. Now they WILL know instantly it's not one of the remaining fighters but vehicles at the town.
As a defender, I'm not exactly happy about the reduced challenge of knowing exactly it's not GV making our field/town flash. Trying to find out "what's happening here?" and choosing my equipment accordingly. Yes, I know I can disable my quadrant, but there is little point to it when everyone else at the base does not.
In the past, adventurous players took their M3 went across one or more sectors to an enemy base without a GV spawn, to fool the guys looking for goons exclusively. 6k away from the defenders the clipboard will now scream VEHICLE!. And yet another thing I don't really have to worry now about anymore as a defender. This is why I also am against any kind of GV darbar. And I am NOT one of those m3 sneakers at all. I hunt them.
IMHO, there is a German word for this innovation: "Verschlimmbessern" - making things worse by trying to improve them.
