And I hate the DOS ruleset to the point where I can't play those games. =)
That said, BG3's combat is awful even from a D&D point of view. It's like playing with a DM who doesn't understand how stuff works.
Luckily for DOS fans, there will probably be a DOS3 after BG3. BG3 needs to be more D&D though, it's not satisfying as it is.
