I would love improvements as much as the next guy, but must say that at this point, BG3 is the best CRPG D&D combat experience I've had.

BG1 & 2 combat was a huge chaotic mess, and you'd spend most of the time pressing space trying to keep your characters from doing something suicidal. It was terrible. NWN was better, because you only controlled one character. I've been playing Pathfinder on and off, and for all the care taken to respect the tabletop game, it's frankly a snorefest. Everyone standing in a big pile, hacking away, and like BG1 & 2, you primarily have to time your healing potions. BG3 has me constantly thinking about tactical advantages, which to choose and which could backfire. That they borrowed a bit from their own games (D:OS), is forgivable in my opppinion, because those games worked well as video games. But I have never played 5e around a table, and perhaps that makes me easier to please. I just don't think it's entirely bad to make the game a fun experience for the average player, first and foremost.
