I think that is a problem and should be treated as such. BG3 should not be the combination of D&D and DOS, it should be pure D&D or almost it. Just remember how the first gameplay reveal was trashed for looking like a DOS mod. The majority of RPG fans are more into D&D than DOS, so the developers should take that into consideration.
The first gameplay reveal was met with overwhelming positivity, as has been the general consensus of the Early Access so far. Not everybody shares your opinion, and the circumstances seem to be as such that most people don’t.
And I said BG3 was a combination of BG and DOS, not DOS and D&D. The elements from DOS I am referring to, such as turn based combat, open ended quest design, system driven gameplay with lots of room for improvisation, and the way party interactions and multiplayer are implemented are not mutually exclusive from D&D, so your distinction (whatever you intended it to be) isn’t applicable to what I’m talking about. In fact, these elements are all very much a part of D&D, so in many respects BG3 feels to me more like D&D than BG 1 and 2 did.
