Sigh, Soda...
NOE flying is actually both very difficult and great fun. Right now you can take out the 'dar with an arado and people will just not notice. NOE-dar attacks aren't going to change much.
However: a single tiffy taking out the dar like that? Damn, that's gonna be a good toss-bomber.
Addressing your points:
1. Yes - random NOE objects such as lone-acks etc, stand-alone dar towers, would all be great. Strat objects, that mean the ground isn't just a place you to get away from it all - you need to learn the terrain.
2. That's very Air Warrior. I think HTC try to minimise the amount of automation in a game and want to leave it to the players to announce 'Alarm 35!'
However - it might be nice if HTC made players at a field that just lost it's dar hear a little "radio-going-dead" hiss/squeak/pop type noise, and perhaps then garble some of their radio reception (make it a combined dar and radio hut).
3) No way there man; those people are NOT engaging the field, which is why they survive the ack. A tiffy or a bomber trying to attack the field is guaranteed death, which right now is what is preventing people from doing NOE. I occasionally try NOE at night in the B26 with 3-5 bombers, but we are guaranteed to lose 1-2 the moment the acks open up, another when the remainder climb the short distance to drop, and anyone who is left after the drop is likely to be -1 eng or on fire. The ack right now makes Ploetsi look like a cake walk.
Pilots are going to need to start spending a few moments in the tower between sorties looking at the world at large. As more strat, and NOE is strat, is added to the game, many players will begin to break away from the "furball and bounce back" mentality and start looking at their maps more often.
4) Not a chance. The sector bars indicate there are enemies present, having dar for a field that has no dar represents something incredibly unrealistic in even more unrealistic way. Certainly while you are in flight, you can see the planes you can see. Any planes you can't see shouldn't magically show up on your map to simulate you being able to see them, because you CANT see them.
5) Hmmm - I don't recall hearing of A6Ms or Spits that had that kind of capability.
Soda...
Most of these ideas seem to be based around the concept that NOE will give players the ability to fly undetected therefore we must make them detectable.
Right now very few folks do NOE because with pin-point radar-precision tracking, you are incredibly vulnerable flying on the deck. Making NOE a viable option by making it undetectable will ADD NOE to the game. Making it detectable again will simply take it back out again.
But you are totally missing something.
In this here dog-fight simulator, there are people who want to fly NOE. There are also people who like flying "scout" and "cap" sorties, only they don't because there's diddly squat point to it right now.
If you can add NOE to the regular flying activities of pilots, other pilots will begin to adapt. More pilots will fly low-level scouting/defensive sorties, rather than automatically pointing their 109 at 32k every time they take off.
And NOE attacks generally only work against a field that is inactive. You try and fly NOE against an active field and they see your dot coming; you have no E, so they only have to have a couple of k to be death on a stick for you.
This will cause a widening of the front lines. Hopefully it will encourage more player to fly more often given a wider variety of missions; perhaps it will bring players over from WarBirds who miss the sorts of daring low-level raids that 617 used to fly (
