Many times, it just feels right though. All this decision making by the AI to run away from a fight based on Morale, Fatigue, Damage levels of the aircraft, damage levels of the pilot, ammunition or fuel level, distance from home field, proximity to front lines - is already coded into WOFF in a realistic and balanced manner. However if you want an arcade sim then go to workshops select AI always engages and enjoy your arcade sim.
