The suggestion here is that a public note is visible when it is within scanner (not sensor) range. That’s the larger of the two spheres, meaning that the note is visible sooner.
I know the plan is to eventually have alliances, and in-game messaging. What I propose is a stop gap. In A2 we could use all the fleets we wanted, so sending 1000 scouts out to act as fence posts was fine. With the new fleet caps that method no longer works. The idea here is to give players a way to indicate borders if they so choose.
This would have no impact on fog-of-war. You can already see a fleet is listed as a UFO when in sensor range. I’m not suggesting that the fleet details be made visible, just the public message. If a player chooses to but their name, fleet info, or other details in it that’s up to them.
This would be giving a ship the ability to broadcast a message out to anything in scanner range, and the only people that would use it are ones that want a message heard. If don’t want to broadcast, then don’t. If there’s no public message then fleets work as they do now.
