It seems there's a lot of discussion both here and on the BGG forums about the viability of the Lambda. Based on my own (very limited) experience and what I've heard from others I wonder if giving the Lambda a rear firing arc would have broken it or made for a more balanced ship?
In regards to the rear firing arc I wouldn't suggest a full powered rear gun, but maybe a 1-2 dice attack since the Lambda clearly has more forward facing firepower. I also realize the Anti-Pursuit Lasers were supposed to be an answer to the limited maneuverability and to complement the full-stop maneuver, but canonically it would make sense for the Lambda to have a rear firing solution. It's slow, has no K-turn and is very vulnerable to flanking attacks.
What do you think? Personally I love the Lambda and I'm interested in finding better ways to use it in my games.
