Fair enough. I will capitulate to you here - this is where we have a preference difference. For me if the launcher is unloaded it should show the launcher values. If its loaded, it should compile the information that relevant to the ammo being shot as the top value.
I think where I am fighting back and forth is that a turret will have its tracking stats updated by ammo. So these stats combine in the fitting menu. With missiles the missile is considered separate from the launcher.
