The Crew Extraction Beam is an interesting idea, but I think it may a bit too limited as it stands. Burger's earlier comments on the comparetive effectiveness of weapon traits are well taken. Combine that with the lower range and restrictions on use, and what resons would a player have to take them over Anti Matter Cannon? I suppose you could make an argument for using them against space stations, like Mass Drivers...except space stations don't have crew scores.
