That's very true, and if you know my posting history I was vehemently against the idea of the FSS for
years. But I've been converted to the new way of things now TBH.
In my subjective opinion, exploration has become more enjoyable precisely because there's a "skill & judgement" thing now; "According to the FSS frequency bar, there are some Gas Giants here, there are also some icy, rocky icy, and rocky planets here. There is also at least one metal rich." - in which case if I'm in the mood to investigate, I'll scan the gas giants to see if they have moons orbiting. If they do I'll then scan the moons becuase you never know, they might be interesting. This gives you their colour, their orbits, volcanism, if they're landable, basically everything you need to decide if there are any owrth visiting. Bonus for me is if there is a gem of a moonlet with intersting canyons and volcanism, I then can decide to fly up to it and bomb it with probes.
Then there are lovely systems; "According to the FSS frequency bar there is at least one Water World - but it's right on the line between Water World and Gas Giant so it's also likely that's a Water Giant" , or "According to the FSS there is at least one Earth-like World here!".
So, yeah, I personally have been converted. I like this stuff.
