Ahem. If the NDA/waiver wasn't so shit, then I'd have already told you this
Advanced Atmospheric Exploration - see ships in production, destroy ships in production, wipe news.
All of these are bad ideas, especially the last one which is horrific. Imagine coming back to your planet after a day off, only to find yourself without any roids, ships or news to explain how that happened. Mr Newbie would probably quit on the spot.
The idea of
not being able to see ships in production has always made attacking that bit more interesting - planet scans can be vital near the end of the round to see if your target has built ships. Of course, this requires though. You're just making things too easy for people (remember that there'll still be alliance scanners).
Advanced Outerspace Techniques - find out launching times of pre-launched fleets (bad idea), re-introduction of mil scan.
Bad bad ideas. These are both good changes made in PaX, please explain why you want to bring them back
