In my second post just a bit under the one you quoted I gave an example of how the situation could happen (B-Wing + SD + DTF). But I admit "plenty of situations" is an exegration. I failed to include the extre die from the stealth it self when I made that statement. Sorry about that.
That's why I'm pointing it out. By the time the B-Wing with DTF has drawn enough crits off of other ships, while somehow avoiding being shot at, that the agility lowering crit lands on it I'm afraid that after the "no defense" attack goes through there really aren't going to be enough hits left that I'd be too worried about it.
