There is no reason to assume Larian knows how to design *all* games. They have had huge success with DOSI&II, designing a type of wacky, whimsical game that is nearly class-less and characters have multiple actions per turn. This game here, BG3, is Larian's test to see if they can design a game that isn't DOS. Specifically, if they can design a game based on 5e.
Re: the interview you quoted 1.) grazing sounds more balanced than Larian's current implementation. So this is not a point in Larian's favor. 2.) again, opinions.

I think you're overestimating the fun of dodging and missing. I don't think most players find it particularly enjoyable, and it's exacerbated/amplified in games like the new XCOM where players are constantly in stunned disbelief at the RNG.
The interviewer thinks Josh Sawyer is underestimating the fun of dodging an missing. Josh explicitly "thinks most players don't find it particularly enjoyable"
