I wouldn't use something like this in any of my games. To exploity and to much micro design/missiles needed for me.
Yes... if you really want to exploit the mechanics then build one FAC with a ton of launchers, one FC and then multiple versions of the same identical missile. Each missile will now become their own salvo...
Have some missiles just be slightly faster than the other, just by a tiny fraction and stuff it full of armour and no warhead.
