Max rank Light Hull has
+4.5% speed
+20% turn rate
-2% hull
Seems a bit useless as it not only has a -2% hull penalty, but also stands in the way of substantial gains in durability.
Add to the Light Hull, on top of existing bonuses:
Acceleration (+20%?)
Reduced afterburner energy (-10%?)
A lighter hull should improve all handling aspects across the board, but it’s difficult to summarize the benefits of better maneuvering in a concrete way besides ‘gut feel’ and lots of recorded game data
