I get what you are saying, but I very much disagree with it. This is a player issue, not one of DM or setting. I and my players have been playing for 20+ years. Two of us for 30+. We still have lots of fun playing humans, elves, half-elves, dwarves and halflings(one of us anyway). And we've played 95% of our campaigns in Greyhawk and Forgotten Realms.Maybe I'm not explaining it well.
My point is that if you magicaly popped into a random D&D table you will very likely land in
1) a published setting using 20+year old race and class tropes
or
2) a homebrew setting using 20+ year old race and class tropes
Do that with an average quality DM and you get some boring. And overexposed.
An average DM is plenty fine for enjoying these races and tropes. Some players get bored with them, but they'd be bored with them in pretty much any game. That's their issue and they should find a kitchen sink game(and there are plenty out there) where they can play catmen, turtlemen or a walking chair if that's what they want.
If the DM isn't explaining the setting during session 0 to people unfamiliar with it, that's a DM failure.Most of those setting use human, dwarves, elves, halflings, orcs, gnomes with slight twwist. The lore might be different but not enough to explain at the campaign pitch.
There aren't completely shifted in tropes like a Dark Sun where you have to explain differences before Session 0.
