Pretty spot on on everything, I guess it's becoming clear changes in gameplay such as disengage as a bonus action to everyone has been really breaking the game flow so far in combat.
I also agree that it doesn't have the feeling of the old Baldurs' Gate games, and it doesn't come from the combat being turn based at all. To me, it comes from (as I've stated in other posts) the lack of class and character flavor mostly. As for the writing itself, I feel it is a bit too early to judge it but I'm not sold on the companions at all (it doesn't help that they're not friendly at all) and I feel more classic fantasy tropes would have been better to start with and to expand upon first.
I hope the writing isn't fully implemented yet - in the encounter with the wounded mind flayer they stayed there, like statues - in DA, they interjected a lot, perhaps even too often.
