I am generally able to separate the story and character introductions or motivations as presented, from the story I tell myself while playing the game, since that latter is way more ad-lib, but here in BG3 it's tougher. I do think more goes into the Character (writ large), than just the story of the character though or their subplot, provided they're in the fold. Faldorn is a good contrasting example going from BG1 to BG2. In BG1 she was in-the-party (as basically the antipode to Jaheira) both true neutral and the same VA, but with different angles. Harper fighter/druid communitarian vs Shadowdruid (proto-avenger) who's way more lone wolf about it. In BG2 we got the continuation of the Jaheira saga in a big way, but Faldorn was relegated to a boss fight nemesis (likely for Jaheira to handle) in the Druidic challenge in later chapters of BG2. The druidic stronghold was generally acknowledged to be among the weakest in BG2, but I think the Faldorn thing also played into it. They teased us meeting like literally every single companion from BG1 in BG2 except Khalid and Dynaheir who got got, but then of course only a few could actually be recruited. Jaheira and Minsc on team good, Viconia and Edwin on teams villainy, and Imoen of course but she hops in and out. Shadowheart and Minthara are basically Viconia's archetype sorta split across two characters, so those angles are both sorta taken care of from a visualization and class mechanics standpoint, but still there was something cool about just seeing Jaheira in a new edition implementation right? Trying to tease out multi-class sub-class angle or spec the abilities and feats, all the itemization stuff and party comp stuff. It would have been cool to see that for Viconia, and then she could also be a story delivery vehicle for the villainous endgame the way Jaheira does that for the heroes.
