Why not? Forgotten Realms are quite recognizable, it's always a way to attract more players.
This isn't pure 5e and most people probably don't care. Certainly the WotC doesn't care.
I disagree with that.
I doubt many people who were lured into buying by the promise of a D&D experience are all that satisfied with the game.
And as for the Forgotten Realms I don’t think that saying that a mage is from Waterdeep or throw Volo around is enough. Personally I don’t get any FR or D&D vibe from the game or its characters at all.
