I do agree that lack of background impact on dialogue’s is disappointing. They added specific inspiration quest but I failed to engage with the system. I didn’t find inspiration points that useful so far, andI tend to forget about backgrounds existence until I get pop up for getting an inspiration point.
Larian early on stated they don’t plan to add extra dialogue options for backgrounds. Your suggestion to have some of the class specific options be shared with classes is interesting, but I am not in favour of it.
First of all, BG3 already homogenised classes too much for my taste - having class specific options be available to other classes is not something I like the sound of. More importantly, I think such change would encourage unintuitive meta gaming. I surely, with a system like that you would never want a bard with entertainer background, as you wouldn’t gain much benefit from it. At the same time, picking a background not fitting your class (to maximise the benefit) would reward choices not to the class’s strength through inspiration system.
