The entire D&D 5e system is a complex designed with pen and paper gameplay in mind, so Larian has a challenge on their hands to translate it into something that flows well and is fun on a computer. The dice rolls themselves, I'm less concerned about. Whereas some games may place a static skill level requirement to pick a lock, with D&D you are given a chance to succeed and fail based on your skill and there are numerous ways to influence the outcome (ie. 2nd level spell Enhance Ability) that promotes teamplay on top. Beyond that, Larian has stated they are mindful of the binary nature of success and failure and that they have gone to some lengths to implement a system that doesn't unduly punish players for bad luck. This would be inducive to better game flow and lead to less save scumming. I'm a shameless save scummer, but would love to explore what interesting twists and turns the dice roll might take me in BG3.
