Hmm i think its problem cause people wanna have gunship and gunboat all in one.
YOu have to choose for what purpose you will use GB and its easy. Put 6 solaris and youll get anti fighter cap support vessel in military engagements. CAP do real damage zyou guard his a ss .
Or heavy combo with cerberus and pulses (my choose) for playing in group with bomber for cap assault or pirating tranports .
Zapper turrets are good idea but need to be redesigned to fire focusly.
