Variant human is part of the PHB, so I'd expect we get them as part of the full game.
In my opinion humans are fine. For pretty much every class, they are among the stronger choices.
Instead of randomly adding buffs to humans, we could also ask Larian to not ignore the drawbacks that some of the other races have in DnD. E.g. Drow should have disadvantage when attacking enemies in sunlight. Gnomes and other small races should have disadvantage when attacking with heavy weapons like pike, greatsword or heavy crossbow. Halfelves shouldn't inherit the magic of their elven parent.
