To add my 2 cents. Humans are almost as Terrible as Dragonborn are.
Their features are very lacking and the only thing they are good at is being a wizard or sorcerer, as they get armour and shield proficiency. However, considering Half-elves get the same + better racial features, there is 0 reasons to pick humans, ever.
Variant Human wasn't OP by any means, as some races have got some really powerful features. Instead now, humans are between C tier and F tier, same as dragonborn. These 2 races, have got the least going for them, especially in a game, so full of magic items.
