I think the heritage of Bhaal or the image of the BG1+2 games in mind of the fans are not suited for a BG3 story. You followed a corrupted path in the first and second installment in the world of forgotten realms, a part of D&D. Players learned classic P&P experience. The game master was scripted with dice decisions while for battles.
WotC decided to give this franchise to larian. I asume if you look at the roleplaying market no other game engine like the one from DoS2 combines a good orientation in three dimensional turn based setting with the possibility of a truly handcrafted grafic system. Clearly there has to be a divide between world of warcraft and so on mass market games and individual concepted storytelling. But if you look backwards to the great games series of might & magic: the mandate of heaven, ultima 7 or wizardry 8, there is the must have for D & D to reorientate to its core values: turn based battle on a turn based grid and in different pros and cons to use the altitude levels of the environment, for examble the higher the stand of an archer the more distance his arrows fly. That positive effect BG3 from larian will have.
What it cannot be is to continue the story for god players from the end of Throne of Bhaal. There was a cut, an ending, a story ended and it was finished. I personally enjoy the fact of fresh wind and a good new start for the series of Baldurs gate with a larian interpreted part 3.
