Couldn't have said better myself, you know the worst part of it all? many of the things in 5e (such as many of the missing racials) aren't actually difficult to implement in a game like this, so it really comes down to either Larian hasn't has the time to implement them or they chose not to because of "balancing" reasons.
My main concern is that making the game less 5e is a deliberate decision. If so, I'd like them to clarify, because what I'm expecting is a pure D&D game given the title.
