[Edit] I totally put this in the wrong place. Could a mod move it? My bad!
These are two small bits of behavior that can be easily seen on a Medusa, but are probably universal in some way:
1) Bomb(er)s steal the shield facing. Fight both a hound and a piranha wing in the simulator, letting the AI fly. If they flank (they usually do for me) the AI will almost always point its shield at incoming bombs or the bombers - even in the situation that it is many seconds (5+) till impact (or that the bombers are not even firing) and the Hound is firing directly into the Medusa's unshielded armor.
2) 'Phase coasting' The AI will use the phase skimmer to speed up while flying at 0 flux - but will not coast during/right after the skim. The net effect is a surge forward followed by a significant bit of time spent at base speed before accelerating again. This also happens on a wolf.
Variant I used to test: 2 lmg's in front universals, 2 pulse lasers, 2 AM blasters in forward turrets. Hard shields and flux capacitors, 20 vents, 10 capacitors.
