Hmm.. strange. Not sure why she is listed as 32 points. Might have been a mixup when I made the list in squadron builder. He definitely played it at 100 points.
Yeah, I think I would have struggled less if Norra hadn't been constantly double stressed. She died last and put up quite a fight, more often than not staying at range 3 and putting asteroids between her and the enemy.
Because we were playing the flechette cannons wrong.
THis might well be a big part of why you lost. Getting Norra double stressed kills her pilot ability almost entirely, and her pilot ability is GOOD. Before you do anything else I'd suggest giving it another try with the rules understood correctly by both players...
