Should work against one squadron in the firing arc. For when you really, really want to pop that 3 Hull Scatter Ace?
Theorycrafting a potential attack from a ship with a 2 blue die anti-squadron armament, with this combo should look like this:
Blue-Blue-Red-Black +Blue set to ACC+ ConFire
6 die agaisnt one squad from a ship. #Bye
If you add a black die as ConFire your average damage against the squad is 3, with a 51% chance to roll an accuracy somewhere, before the LTT reroll. If you do 2 black die with LTTs instead of the red you get an additional .25% average damage, but the chance for that 2nd ACC goes down to 44%. You're not likely to have Ordance Experts (opinion, I have no idea if there will be a viable 2 blue anti squad ship that also boasts two Weapons Team slots...)
