Oh yeah, none.
Well, Darkon is pretty accepting of demihumans (by Ravenloft's standards), and you might avoid (excessively) distrusting glances as an elf in Sithicus (unless you come by those little halflings with particular culinary tastes).

Ravenloft is a xenophobic, low-magic setting yet it hasn't stopped people from playing non-humans or spellcasters in the past. Nor should it.
Point taken. I agree that warlocks are as playable as any other arcane class. And eladrins should face the same challenges as your standard elf.
My main concern is with the less than subtle races. Calibans were an elegant solution for incorporating a race with similar mechanics as the half-orc, but the current edition's tieflings and dragonborn, while appropriate for a high fantasy or sword and sorcery campaign setting, pose quite a challenge when it comes to fitting in Ravenloft.
I mean, I can see a few individual tieflings' physical characteristics justified as the consequences of dealing with outsider entities or failed powers checks, but it becomes significantly more difficult to do so with a whole race of them.
Even more so regarding dragonborn. And the mongrel-man trick has already been used...
Of course individual tastes may vary, and you may argue that it could be as feasible to incorporate drows, githyankis, muls, half-giants or thri-kreen, but that doesn't mean they would mesh well with what has come to be Ravenloft's standard flavor (if there's such thing).
Jus my two cents.
