So I had 2 games on vassal tonight, and both featured a key moment where I had extremely bad luck that could have come back to cost me the game, but luckily didn't since I was playing well overall.
First game
I had one attack round where I had 2 ships get 7 out of 7 hits thanks to both having focus and predator. Now some might say that's good luck, but when you have both it's not that unlikely really. My target of attack was an e-wing with stealth and the agility astromech for his action. He proceeded to roll 7 out of 10 evades so not 1 hit got through and his stealth stayed intact.
Second game
I had a 4 dice attack on carnor jax with no evades or focus to back up his defense, but did have stealth. Because it was range 1 I couldn't use my focus, but did have predator. I proceeded to roll 4 blanks, and then did my one re-roll into a 5th blank.
