Because it is bigger.Well an eagle or sidey is ok. Sliding scale
But having a full on fighter on, or piggybacked onto a vulnerable ship that's fully freighted is a fab way to give said freighter a fighting chance against murderboats. And a whole new angle on powerplay shenanigans.
If an eagle or sidey why not a fdl.?
How about it being the only ship with size 4 turreted weapons that aren’t nerfed because it is big enough that the turrets can be properly built.
