Honestly my only concern is Larian made it clear this is a one off...
Yet nearly every DnD game ive ever played was better off with big story DLC... neverwinter nights and baldurs gate really benefited from dlc but Larian has said its going to be one and done...

Id be cool with that *IF* they were going to make BG4 once they were done with postlaunch patch frenzy of BG3.
