Copy-pasted from my Reddit post, because I'd like to see it generate discussion...
Okay, technically, it wasn't a one-shot: he went from 100% untouched to one hull left, and I intentionally avoided the ram-to-kill because he was sitting in Home One's broadside. Still counts.
I was second player, and the objective was Hyperspace Assault. Tvayumat ran his nose right up against my exit point, so I dropped the MC30T out of hyperspace nose-to-nose, with the double side arc into his nose. His ISD tried his damnedest, with six fighter activations (4+EHB+Tarkin bucks) and then a close-range shot, and then a ram. The salvo dropped me to essentially no shields and 2/4 hull left.
Then, I ripped into him.
It was an MC30 Torpedo Frigate (the blue/black one) with Intel Officer, Turbolaser Reroute Circuits, ACM, and Ordnance Experts. The nearby MC80 was Home One with Ackbar aboard.
First shot was a terrible 6 damage (two from a TRC'd Ackbar die), with two accuracies (one from Home One) on the redirects and Intel Officer on the brace. Could not get a single goddamned black crit on 8 rolls (3 normal, +1 CF, then OE rerolled them all fishing for the crit). He opted not to burn his brace, and took two to the hull.
Clearly, all of the best gunners aboard were on my starboard side, because they then ripped into the nose, dropping 10 damage plus ACM. The (sole) Home One accuracy shut down the brace, and he was able to redirect 2 points to one side, allowing 8 damage through to the hull for a total of 10/11 hull damage.
I don't think there were any particularly terrible/amazing rolls involved. All of his fighters hit, as I recall, and he rolled 6 damage + 1 acc out the front of an ISD-1: almost exactly average. My shrimp's total of 16 damage was actually a couple points below average.
The takeaways here:
• Shrimp are the cannoniest of glass cannons right now.
• ISD's can die, vigorously.
• For God's sake, don't pick Hyperspace Assault or Advanced Gunnery (which would have been functionally equivalent) if your opponent has a pimped out MC30.
