Given the popularity and critical acclaim for D:OS2, saying anything bad about it is about the same as saying anything bad about having sex.
A fringe opinion.
I liked DOS2 a lot, however I see no reason for DOS2 features to be in a D&D game, specially when the main criticism about the game so far has been this frankesteinian mix between the two. Solasta proved that pure D&D plays better. It will still be made by Larian if they remove the DOS2 stuff.
