And please no more no more over the top edgelord companions (but looking at the datamining it feels like i am shit out of luck regarding that wish)!
This is, as people on these forums have said before, a symptom of the Origin system, same as in DOS2. To justify each party member potentially becoming the main character, all of them had to be designed with some rather over the top qualities to justify them taking the lead. But there is such a thing as over-designing to the point where they seem like they're just shouting over each other for attention, rather than synergizing.
But trying to tell Larian to ditch the system and focus on things that everyone can actually potentially see in their first playthrough, instead of shoving exclusive cutscenes behind each of the companions becoming the main character for an attempt at adding replay value, is probably the most futile fight of all.
Probably the greatest irony is that player characters like the Warden, Inquisitor, the Watcher, the Baron, and the Commander of the 5th Crusade are probably way more memorable than any of these origin characters, and also mean vastly different things to people. And none of them diminished the quality of their fellow companions at the same time. (And let's face it, none of the DOS2 characters lit the world on fire, and I doubt BG3's companions will either.)
