But have you considered how many macrotransactions they can fit in it. Escape from Tarkov was selling some crap for $250 a pop and it didnt even have everything.
Youre thinking "how can this game be fun" which is not the consideration of the people in charge of coordinating a project like this. They're thinking "how much money can we get for as little creative work as possible"
Any race can be any class, don't worry it's not that kind of game.
Dragonborn came to Faerun only recently. Magic nonsense from changing editions. If you know a bit about forgotten realms lore, Aber and Toril and some crossover stuff happen.
If you wanna RP stuff, think about how your character learned to be a druid! BG3 gives you plenty of reason to be travelling with a group of weirdos, so you don't have to worry about jiving with party members. You all have a really good reason to travel together and work towards a common end.
