The FSS complaints are far more fundamental, the key complaint from at least some quarters is the addition of poorly thought out (and badly implemented) mechanics as a blocker for an activity that did not need it previously. It is roughly comparable to erecting a brick wall across a public right of way with a rope ladder on either side to get over it when the brick wall is arguably unnecessary.
That's primarily a matter of opinion. I, for one, don't think the base mechanics are poorly thought out. If they were
genuinely poorly thought out, I wouldn't be able to quickly find the interesting orbital heirarchies, planetary alignments and other phenomenon I'm most interested in.
It is true that the FSS does provide a
bit of a hurdle to determining if a system is "interesting" to you. Compared to holding down a button for a few seconds,
any activity that requires
active input would be considered hurdle.
Unfortunately the ADS had to go because it's just not compatable with FSS. FSS though adds a 'fog of war' function that -- believe me - when ED first released and a fog of war didn't exist, people were gutted about missing out on. I think if ADS were to be restored it would have to be foggy in some way.
The ADS is no more incompatible with the FSS, anymore than getting information about a system someone
else has turned in data for. Different people consider different things
interesting, and personally, I think there's far too few actual
exploration tools to choose from. As long as its an
optional extra, it'll neither pick my pocket nor bloody my nose.
The ADS honk wasn't exploration. It was what you did before you started exploring
And for many players, once you'd honked, there was nothing
left to explore, because the ADS had done
interesting parts of exploration for you.
