Hopefully this question wasn't already asked, but yesterday we started EotE by the beginner's game set. There was one question about the deflector shields worth to think about and I didn't have an explanation yesterday.
In SF movies like Star Trek shields are blocking shots until they are taken out. In EotH the deflector means a setback dice and sometimes a shot hits and sometimes not. How would you explain, why sometimes the deflector works and at the other time a buzz goes through it.
It wasn't a big deal yesterday since my players are reasonable enough to accept it as a game mechanic (we had a great time by the way), but since last night I'm thinking about it
