Well, for me the "miss out" option can be meaningful, it depends where the failure leads you to. My gith wizardess fumbled every roll with Shadowheart and couldn't get her to join the party. Later on
a befuddled Shadowheart joins you at the camp, implying that the githyanki artifact she is carrying is influencing her, because it wants to be 'near' the main character. I found this reveal to be quite interesting.
But I agree that the dialogue needs bug hunting and tweaking.
