I'd remove Tieflings and Dragonborn as races all together and certainly put Elves above Humans. It's funny how people have been saying that Gnomes are now superfluous, whenever I make up a world in my own head, it's the Halflings that I struggle to fit in somewhere, their culture is usually just Human to me.
So true. Just look at letsplayers on youtube. Everyone is running a tiefling. It's quite annoying. Dragonborn are just as cringe. At least Half-orcs would be flavorful and not the special snowflake race. As for halflings, they always strike me as peasants. They are basically small statured peasants. They still have more validity then gnomes though.
