The amount of bad-faith takes here is pretty astounding. There is no doubt that Larian advertised the game as a Baldur's Gate game, based on the 5e ruleset.
Asking that the game's mechanics be as close to 5e, in EA, is not unreasonable. Larian adding its homebrew to the game is also reasonable, to the extent that it does not break the core ruleset the game is based on.
Currently, Larian's homebrew is "breaking" the action economy, it is creating too much overlap between the classes and is removing a lot of the tactical choices (by providing significantly better (read OP) options).
In short, the game balance is all over the place. A somewhat straightforward approach would be to align the game with 5e, and then apply homebrew were necessary/fun. What's so hard to understand in that?
Well said. As many others have expressed, I wish this forum had a "like/upvote" feature.
I'll add: obviously Larian chose to use the Baldur's Gate name and D&D 5e system at least partly for the name-recognition to boost sales. They are a company; they need to make money in order to exist and create new games. This is not a bad thing, but it is a thing and denying it does nobody any favors.
