NOE missions are easy to fix and still allow them to continue.
My idea would be;
1. Set radar detection at 100' altitude instead of 500' like it is now. Or perhaps decrease the altitude required to maintain NOE status the closer you approach an enemy airfield, vbase, or strategic target.
2. Disable to use of auto level of any kind under 500 feet, that also includes setting auto climb to max speed to mimic auto level. You want to fly NOE, go ahead and do at least a little work.
3. Enable zone ENY. Make the tolerances much higher than normal ENY, so unless you're attacking a base within 50 miles of at least a few enemy airplanes you will be stuck in early war aircraft.
I feel a lot of the time missions are more interested in avoiding conflict than truly interacting with other people online.
