If your players are cool with that, great! Y’all have fun the way you like. Just, you know, make sure they are indeed all cool with it, cause there are plenty of players out there who would not be. If you’re up front about the fact that you intend to change the result of dice rolls when you think it will make for a better narrative, and that you won’t be rolling in the open or disclosing when you change a roll, that gives players who think that sounds like a bad time the opportunity to leave before it can become a problem.
