Let's make it simple.
I'll be the player.
My First Choice of character is a Half Elf Fey wanderer Ranger
Second is a Goliath Barbarian
Third is a Kobold Sorcerer
Then a Drow Arcane Trickster
Last is a Human Rogue
Am I entitled to think that I should believe that I should be able to play one of those, something like those*, or be convinced by the DM that although all of those are bad there is fun to be had?
*assuming I reveal my reason why I want to play it or the DM asks
If a DM told me that the only species available in campaign were goblins and orcs, I would have questions because I don't want to play an evil character or play in a group with evil characters. If I was assured that wasn't the case I'd figure out which one made the most sense for a character I would enjoy playing. The restrictions could lead to some interesting ideas.
