It's amazing how often d4+d6 (wild die) aced on untrained skills. we had one guy roll 3 "6"s in a row (and then a 1) that gave a 17 (19-2) on an untrained skill in the first session. He basically skull smashed a walking dead with a gun butt with no fighting skill in one quick round.
Yeah, I see this all the time. And once you factor in Bennies, the wiff-factor becomes negligible except during really, REALLY tense situations. And shouldn't that be the point? All of a sudden, your character has to rely on that Persuasion skill you decided you didn't really need. Intimidate just won't do. Everyone at the table is watching you. You have one benny left, and you may need to soak. Pray for an ace and roll...
Damn, see that's what makes SW so much fun!
