There is no point in showing everyone's location in SC as USS, that in fact might counterproductive. what we ideally want is a system with closed loops, a reason for an USS to spawn and a way to track down what is happening with the associated gameplay. I don't want to show my location to everyone or just to someone, I want to send a distress signal for a reason, or I want to system to send a mission/goals to another player for something that I did, not something that I'm doing. I want gameplay, not presence, I'd be happy if when I jump back to SC after killing something a USS for degraded emissions shows up in case I left materials or cargo, and this example has nothing to do with where I'm at any moment.
It's not a case of wanting to - it's whether doing so would create more sense of life in busier systems.
And I believe that's the original premise of this thread.
Is there something different about your weapons fire that prevents it being seen in SC as a Weapons Fire Detected signal source?
