You want to have an action for BR or a Token for defence. Without it, the BBBBZ will probably perform better.
I agree that long-term you want to get your actions back. My point is simply that in the short term, pulling a 4K and then a 5 straight to get you right back into the thick of things is not necessarily a bad call. I've done it on Vassal and it surprises many players because they expect you to be focused on bleeding the stress.
Remembering that your offense isn't dependent on actions can get you shots you might otherwise not have had... as long as you remember that you do eventually want your actions for defense. =)
Yup, you've got this exactly right. This is exactly the same reason FCS B's are so deadly, because the offense isn't dependent on being stress-free. It's good if you get that action, but keeping guns on your target is the main consideration. This should fly even better imo. The offense is guaranteed (even if the maximum is less), and these ships will be much better at staying on the table.
Personally, as a long-time B-wing pilot, I'm really looking forward to switching to Imperial and giving this a shot.
