Let's be honest here...the races need some kind of rebalancing. Humans are terrible; so are halflings for example. Why not add something extra to them even if it is not officially in the player's handbook such as halfling luck being a +1 to any roll and humans getting extra proficiency points. Obviously not everyone is going to powerplay but it is only fair.
I agree with adding something extra to the races but I will say that I don't think Humans are terrible. Humans I think are the third after Orcs and Dwarves that make good warriors or fighters in rpgs. Instead of Humans having +1 on every stat, they should have a +2 on strength and constitution. Just like how other races have certain natural abilities like dark vision, resistance to fire, ect., Humans should have something as well. I know in DA:I, Humans get extra 2 points to add to their skill tree and Elves have a resistance to range damage. In Baldur's Gate 3 they can say add hit bonus point for Humans, maybe a +2 on a hit roll or something else.
