Would like to point some observations
1) They use ammo (understandably to stop spamming)
2) Once ammo is depleted they are just useless turret that have no purpose
3) They have lower refire than mortars (same as heavy Mortars)
4) They do a much lower damage than Mortars (BS Missiles)
5) They use the same power as a mortar. (BS Missiles)
6) Less effective vs Ships that do not have components
Currently i see no use to mount them when there are better options available
My suggestion: Lower the power consumption to make it viable.
as much as i would love to see their damage upped heavily instead of power consumption, due to their wonky mechanics about explosion Radius and current disco equipment HP, that would cause weapons and shields ripped apart by missiles
my suggestion is either upping their refire and lowering power consumption while keeping the damage same, or make them with unlimited ammo
