The problem with the HLC BBXX list is that it's all PS 2 and shoots after the PS 3+ Firesprays. You'll very frequently have situations where your damaged ship and a damaged Firespray are in arc of each other, but the Firespray kills your ship before it can fire. At PS 4+ you reverse the situation and start finishing of damaged Firesprays before they can shoot, which makes a huge difference in how much damage you're taking.
XXBB w/ HLC is amazing, despite being PS2. If it's not viable against Firesprays, what is it viable against?
Just so we're clear, that was a rhetorical question.
