I think your choices should have some consequences.
E. g. if you decided to play a paladin with Oath of Devotion then you're expected to be honest, courageous, compassionate, honorable and dutiful. So if you deviate too much from such behavior you should temporarily lose you oath abilities until you atone. Or if you voluntarily do this you have to pick another subclass like the Oathbreaker.
Agreed, I hope we’ll get something like this.
Interaction with NPC's and companions should also be affected by your actions. The general alignment system is too simplified. So it would be better to have a list of personal traits and then get a score in each based upon your actions during the game. That is how others see you and they will respond accordingly. If you have a reputation for being cruel then some NPC's in a tavern will be sceptical while others might see you as a possible asset (like criminals).
I know some games, like PoE, do have that sort of trait score approach and I sort of like it, but would still prefer a means of NPCs responding to what you do that is unmediated by scores in that way, i.e. each NPC would have a potential attitude adjustment (and possibly specific dialogue if they’d care enough to mention it) for significant things you might do in the game that they might reasonably know about. NPCs in particular factions might have broadly similar reactions to simplify this, but there would still be room for individual differences where that had story implications. I know this might sound fiddly, but I don’t think it would be that bad as the vast majority of what you do would impact few if any NPCs, as even if if they had heard about the events in question they wouldn’t necessarily know you were the one involved unless you or someone they know tells them. I would rather have a smaller number of NPCs respond in specific ways to things I’ve done that affect their friends, faction or allies than everyone in the world responding in generic ways to scores (or alignment) I’ve earned largely by doing things it would be a stretch to imagine they’d ever hear about.
Interaction between companions should also be affected by your actions and some might become suspicious and even hostile towards you. E. g. it would not be likely that a paladin companion would accept staying in a party breaking into houses to rob people.
Agreed again. We already see some of this with companion approval plus dealbreaker events (or possible dealbreaker events that we can persuade them out of) in some cases. I’m looking forward to this being further developed.
I don't think we will see any of this in BG3 because the game is too far along for Larian to add such mechanisms beside what they already have.
I think the mechanisms that would allow Larian to do what I’d like, at least, are already in place though would need some development. There’s companion approval and NPC attitude, plus responsiveness of the world to character tags. I don’t know whether the game already attaches tags like “Saviour of the Grove” or “Butcher of the Grove” to your character when you take certain options, but it feels as though it could and then have relevant NPCs with specific dialogue or actions for characters with those tags. I can’t imagine it would be hard to have some tags, like Deceptive or Cruel to be earned by showing certain behaviours a number of times. Though I still have my reservations about having NPCs respond to traits rather than specific events, it’s one possible way Larian may track adherence of Paladins to their oaths.
