No when the advanced space pirates dodge your missiles they are not actually dodging it... Its just there linear attack pattern fooling you.. They don't detect and dodge its just there time to jump to a new location to start firing...
Theres a big difference between these attack patterns..
1) space pirates - Fire, Teleport/jump to new location, Repeat
2) elite - Fire If grenade detected dodge
1 is just simple linear prog, fooling you into the belief of AI
2 Is actual AI responding to your moves
Theres a great difference between the AI on easy and legendary.. GO play it again.. Regardless of how much damage the opponents do they react very dif.. easy oppenents tend not to move at all... legendary will move while firing..
