Something being the "best adaptation of a TT rule set" is not the same as something being "good." For you, that perfect adaptation of the TT rules is what you're looking for. For me, I don't give a damn about the TT rules, and have no desire to see everything from the TT rules be "perfectly" adapted to a videogame. In fact, I WANT many of the TT rules to be discarded or changed, because I find them to be crap. In an ideal world, Wizards would allow a game developer to license just the Forgotten Realms setting and its lore and not D&D rules and mechanics, so that they could make a game using that setting and lore but with completely different mechanics than D&D.
You may not care about adapting TT rules, but both Bioware with BG 1/2 and Larian with BG3 have stated that adapting TT rules to the pc is part of the goal. Starting with RTwP, that requires the abandonment of several mechanics, because they will not work, is a poor choice, plain and simple.
The mechanics of ruleset, are are setup for turn-based combat, it's not even trying to be "perfect" in the adaptation to realize that they do not translate well to RTwP.
