I don't really see where the issue is. I have the same ratio of FC:Guns of roughly 1 FC for every 10 launchers on this ship here.
The "Phase II" fire controls are a bit useless, I have no idea why I wasted RP on designing them and hull space on adding them to this ship. Ignore those. Seriously all they do is balloon out my uridium consumption I need to fix this big time for the next phase of fleet designs.
