One of my players has recently had his eye on the Influence power. I must admit I'm a little apprehensive about the upgrade which allows you to add your Force Dice to all social rolls. The character is getting close to Force Rating 3, and is decent - but not great - at most social rolls already. Since the power allows him to add his choice of either Success or Advantage, it seems that, if he needs to succeed, he will. He's not likely to use those dark pips on every negotiation check (which I'm thankful for), but when he does, it really seems like he'll be almost unstoppable.
Have your groups found this to be a problem? There are a lot of abilities that allow PCs to add Force Dice to their checks, but this one seems like it could be especially problematic. Or it could be a total non-issue.
