Hello Commander Lobstris!
Fundamentally, if we simply allowed NPC wingmen without restraint, it might very well make the situation worse *and* make having wingmen more mandatory, which is not something we really want.
I'm not saying we've dropped the idea, just that it has a lot of ramifications that we don't want to take lightly.
Having NPC wingmen would make the game so much more fun. It would open up so many possibilities. Also, it's more realistic. Fighter pilots don't fly alone. And in a dangerous universe trade ships and mining vessels would have escort.
As it is right now there's no challenge in the game. All interdictions are avoidable. There is no danger in any mission. It can't get any worse. Maybe with wigmen players wouldn't complain so much if the AI was hard or aggressive. Players could choose to fly alone (maximum difficulty) or have a bunch of wingmen (easy mode). Now we're talking.
