Thanks guys!!
Baron, i was thinking the same thing. That B wing is there to soak up fire, also the A wings are there to confuse opponents and divide their fire as well making the ships last longer. Hopefully.
stmack, 3 Bs would be cool. I own 2, but i wanted to use the variety of ships I own and see how that would fare. So far they have beaten a fett and kath list and a howl runner swarm phantom list. the Protos are great at just being a distraction and blocking is a plus! The autothrusters help with their distraction tactic hopefully pulling fire away from YXB formation.
I have another list that takes away an A wing and adds Dutch and Jake for a PS boost.
