I've read a lot of comments (not all, but I have clicked through every single page).
ADS Concerns:
Exploration for me isn't just about "shinies" eg ELW's, Water Worlds. I'm also on the look out for boring celestial bodies that have interesting characteristics, of which that information is made readily available after the "Honk":
-High Gravity planets (You can see how many Earth masses a planet has and it's radius).
-Planets with close orbiting moons, orbiting close to their parent star, or in other complex arrangements.
-Moons that are orbiting within the rings of gas giants.
-Rogue planets (of which I have only found one so far).
None of these really care about the composition of the body itself, and to get an idea of whether a "bland" system might be worth investigating, the current implementation will allow me to quickly pick out a boring system with some interesting arrangements vs a boring system with nothing worth looking at.
I think a decent compromise here would be to have the ADS "Honk" reveal all bodies as before, but without the visual cues...just make them plain spheres (Perhaps though explorers could still deduce a planet type by the sound as done previously however).
ADS/DSS Purpose Clarification:
Just want to clarify this, but it seems material composition (and additional information) of planetary bodies is now part of the ADS system.
This may actually be fairly good news, since if you aren't interested in looking for specific planetary POI's, or getting the new "First Mapped By", all that data is all now obtainable with the ADS alone, rather than the ADS+DSS.
Of course I could of misread the OP, so hence wanting some clarification in a simple question:
"Is all of the currently implemented DSS functionality (planetary information, such as material composition, atmosphere, etc) now built in to the ADS?"
I am mostly pretty positive about the changes, but I can fully understand and empathize with how this could make exploration quite a bit more longer and tedious in certain circumstances. On the other hand, I could also see it possibly working out by being both faster and more satisfying to discover systems in other circumstances, since you could potentially save more time on travel by trading a little bit of time in the discovery scanner screen.
