For the B-wing, I like the idea of the B6 and its composite-beam weapon.
Start with 3 recurring charges, and it takes 3 to fire it. Use the bullseye arc, 6 dice, range 2-3, and only focus results can be modified by the attacker (no dice re-rolls). Weapons disabled and ion token after you attack with it.
Basically, the bugs aren't worked out yet and some of the features (targeting computer integration) are not implemented. It could be huge or it could be a dud. And using it puts your ship in a not-so-great state. It is a prototype, right?
