But we aren't talking about table top. In 20-25 years of playing CRPGs I cannot recall ever having dice rolls on screen, let alone every five minutes. The fact that you are on first name terms with your dice is not a compelling argument for their inclusion in a computer game or for anything else really.
This game is clearly inspired by tabletop and the vibe Larian has been pursuing is one of simulating a tabletop experience. Part of the process for making the game was a bunch of people doing the story like a tabletop module and then using that as options for actions.
