Recent game playing Rainbow TIE/D (Defenders with one each of Tractor Beam/Ion Cannon/Flechette Cannon), and after he unloaded plenty of damage onto my poor PS1 defenders, I had my shots. First up, the tractor beam dude. I eek out 2 hit results against Vader, who rolls evade-focus-blank, with a focus token. I just shrug at him and say...
"You can spend the focus to dodge this attack, but there are more shots coming in... and really, it's just a tractor beam token."
He nods and lets the token hit, and Vader gets pulled a little closer... turning all my R3 attacks into R2, and Vader into a glorified X-Wing. By the end of the turn, his TIE Advanced has ion, stress, and only 1 hull remaining. The rest of the game went about the same - I lost my Tractor D in the first crossover, but his other 2 ships - a Bomber and a TIE/SF - didn't fare well against the other two troublemakers. Once I had them pointed away from me, the combinations of Ion and Stress were enough to ensure that the only shots coming in were mine.
On a side note... THIS SQUAD IS SO FUN in casual play! I can't see it having much luck competitively, of course (too many turrets out there that can stay out of low PS arc) but for league night, I think it's going to be one of my longterm staples.
