So, while I have doubts that FD are continuing to collect feedback from what has become a threadnaught wrought with discussion instead of feedback, I'm going to post my two cents.
First off I just want to say, I love the new mechanic; but there are some things I feel can be done better.
The new Discovery Scanner mechanics need to be built in to the ship like the Data Link Scanner
The new mechanic is much more involved than the existing ADS/DSS combo as far as user input is concerned. It's also likely going to be much more satisfying. Because of these two reasons it is my opinion that the new scanning mechanic should be built into all ships. My primary concern here is that I'm honestly sick and tired of being forced to waste a module slot on a Discovery Scanner. Back in the day this wasn't a huge issue but now we have a significantly large portion of modules and finally having a built-in tool for exploration on all ships makes sense and would give players more flexibility in fitting. Something that is sorely needed as is evident by the massive amount of requests to combine the ADS/DSS or allow us to split internal compartments to fit more smaller modules.
It doesn't make sense to remove the current ADS mechanics
The introduction of a new technology in life doesn't invalidate or remove older technologies. More importantly introducing a new game mechanic should not force players to stop using an existing one. Instead the new mechanic introduced should intertwine with the current method of play.
To that end, keep the ADS with its function existing exactly as it is. If you have the basic scanner built in to the ship as proposed above the ADS becomes an optional add-on that speeds up the process of discovering bodies. For dedicated explorers this means that they will have the option to use a module slot to speed up their process by eliminating the need to locate the bodies by using the ADS, and then use the built-in scanner to perform the new detailed scans through the interface.
The net effect of this approach is that those wishing to expedite their exploration process can, to a great extent; while everyone else gets a huge quality of life improvement in terms of more flexibility in fitting by opting out of the ADS in favor of only using the built in scanner in exchange for a little more time investment on scanning. Over all this would make all aspects of exploration and fitting for it more satisfying for everyone.
I personally would take the approach of ditching the ADS in favor of only using the new scanner because like I said, I'm sick and tired of wasting my smallest class 3 internal on a size 1 module!
The new Detailed Surface Scanner "surface impact" probes don't make sense
At least with modern technology it's obvious that mapping the surface of a planet and locating things is with satellites in orbit. While I appreciate the Imperial Probe Droid-esque approach to finding things on the planet surface, it doesn't make sense to me when you approach things with logic. I hope this is well explained in the codex.
Planetary Static POI's versus "Random" POI's
The listed changes don't lend much insight into how the random POI's will be handled by the new system. When we scan a planet with the ADS are they going to show as potential sites in the right hand column at the top of the scanner? Will random POI's (ground based USS') be differentiated from persistent POI's? These are things that should be done and considered.
