Larian, if you're reading this, this is just the vocal minority. Don't listen to them. Most people are expecting NPCs to behave exactly like the cheese vendor for Classic, and if NPCs do not have radiant dialogue and inventories filled with cheese for sale, then this game will be a massive letdown for the majority of the community.
Sincerely,
A concerned fan.
Larian already said in an interview that they're taking suggestions from everyone, even if it's a minority. At the end of the day, they decide what's best.
I'm not suggesting to mute NPC's completely, but it REALLY gets on people's nerves when you hear the EXACT same line 100 times in the last 20 minutes. An annoyance like that shouldn't be in a modern RPG game.
I find it really damn disrespectful of you to suggest that Larian doesn't listen to me. Whether it's a minority or a majority, it's my suggestion, I'm vocal about it, and some other people agree. Create your own damn topic to suggest against it.
