Regardless if the math checks out or not it is disappointing and not fun to play. I have 17 charisma, and specialized in persuasion proficiency and my rolls still randomly suck for persuasion. I more often than not fail my checks. The whole purpose of min maxing my charisma and persuasion proficiencies was to play a character good at dialogue so I can see the results of my play through. Not be held hostage to having higher than average stats with mediocre results and not being able to enjoy the character I made and lose out on the cut scenes and fail the dialogue checks I am expecting to see. What's the point of having higher than average charisma with extra proficiency modifiers if it still sucks more than half the time anyways? Why is having high modifiers so punishing? It's like I'm fighting an up hill battle trying to break even. Qualitatively, it just feels off and is not rewarding. They need to either make the rolls less punishing, give some hidden boosts, or re-evaluate the dice mechanics. At this point, I have failed 80% of my persuasion dialogues in the game and just don't feel like playing. My character feels like a charismatic dimwit with the highest stats I can achieve at this point in my play through. And I'm against reloading saved games until I get the result I want. That's just not fun.
