i've always thought it was a bit too small. i'm not sure what the fix needs to be. i've not flown one so i'm not sure about it's powerplant but with it being so small i would imagine that it should have a powerplant only slightly bigger than a GB. an agility decrease? it's super tiny, both width and height. i'd almost say it needs a new model truthfullly.
from experience capship weapons are extemely difficult to hit it with, even regular turrets seem too slow to hit them. i bet they could easily just circle around a bigger ship without fear of being hit enough to cause any serious damage.
they are by far one of the most difficult ships to fight. not so much because of there firepower but because you can't hit them.
