I was attacking a Yoral colony with a group of Laser Destroyers, and after disposing of their scattered defense fleet, I found myself facing their ground batteries. I noticed that their ion cannons had the same range as my lasers, and after a bit of trial and error I found that my Destroyers were maneuverable enough to fly one tile in, fire off their lasers, and then jump back out of range in a sort of zig-zag motion. In this way, I was about to attack with impunity despite not actually out-ranging the defender's guns. It took about 30 turns to whittle down the armor, but eventually I was victorious, losing only 1 ship to a defense which should otherwise have been insurmountable.
If I weren't in such bad shape playing as the Humans on Hard, I would have declared that to be a stupid exploit unworthy of my play. But I needed everything I could get with so many aggressive neighbors out for my blood.
Has anybody else found something similar like this?
