Hi Sarah,
I am a bit confused by this statement as it would suggest by extension that human players may not actually need FAOff either to get the most out of their ships.
I d agree FAOff is not a flight mode that would give anyone an advantage "per se", especially if used 100% of the time. There are many obvious situations where that steady control of FAOn is much more advantageous,
But there are also a few situations where FAOff (I reckon) is more advantageous to FAOn, and I see in principle no reason why an AI should see this differently as you say?
For example, any ship with a lower turning rate than her opponent (say a Python vs a Vulture) will probably have a harder time trying to get a clear shot at said opponent which, by definition, may be at her six most of the time. In these scenarios, the best way for the lower turn rate ship to get a decent shot at her better turning opponent is by activating FAOff and drifting away, opening some space, and bringing weapons to bear.
Trying to do this with FAOn can also be achieved but it requires the ship to decelerate and accelerate in reverse while turning, which is a much slower process than simply activating FAOff.
No?
