Easier for people not used to dice systems to understand. It’s immediate and obvious, most non dnd players can grasp it at a glance.
I repeat my point: you could have the option of toggling it off. Both types of people would be happy, then - those who don’t like percentages and those who do.
And I repeat mine... If someone is interested in playing D&D at the table, as BG3 will undoubtedly foster for many, showing the target d20 DC in the combat tooltip, which is essentially the same exact thing as what the dialogue UI is doing, will (most likely) ease the pain of understanding how attack rolls work for a tabletop game. Showing percentage to hit in combat and a target d20 DC in dialogue is inconsistent and more confusing for people looking to play at the table.
