"After you perform an attack that misses, you may perform a bonus
attack."
Never mind the fact that there are no general-purpose damaging cannons in 2.0. If 67-100% of your list can only shoot forward and is Initiative 4, your odds of being able to even take that first shot (and thus even potentially benefit from B's ability) is minuscule in today's I5-6 Ace-filled environment. I just faced a janky squad of B-list unique Phantom/Interceptor/TIE ln pilots with a Bots+1 list. It wasn't even trying to hard-counter my list -- it just did since it cost less than 200 points. There may have been one round where all three of my ships could attack, but if so, I don't remember it. I don't know how I'm even supposed to roll red dice against Wedge or Whisper.
Is the IG-88 key not spending 15 points on cannons? Flying fancy with alternating boosts and target locks while only attacking every three rounds? Being Worlds-level at maneuvering and only facing opponents who aren't? Something else? I have no idea what to even try next.
