Is anyone else super frustrated with the Rebel's defense dice? I'm enjoying the game so far, but even in hard cover my Rebels seem to drop like flies. We just completed a game during which I rolled 22 white defense dice (including several for Clambering, and 3 for rallying). The results were 3 Blocks, 1 Surge and 18 blanks. That was the first white defensive Surge I'd ever seen. In our previous game my results were about the same. So as far as Clambering goes, these dice are great! For defense rolls? Not so much. I know I'm just having bad luck, and the Rebel's defensive Surge means they have a 1/3 chance of blocking, but that hasn't been working out for me.
So my question is, what do other Rebel players do to mitigate their lousy luck/lousy defense dice? I've been very good about keeping my units in cover or out of sight as much as possible and having Dodge tokens. What else can I be doing?
