Please don't put in AI escorts.
It's up to the pilots online to escort those bombers, I feel. In the same way putting the bombers at altitude tries to get players to fly higher, no escorts kind of tries to get players to fly proper missions instead of just fighter sweeps and dog fights over airfields at 1000ft.
If you blue pilots are content to let your bombers come at us unescorted, don't go crying to Goering that they all got shot down
Not to mention the fighter ai routines are still pretty bad....
