For me though it isn't just about the stat bonuses. The half Orc has minimal benefits compared to the other races.
Dwarves have their stat block, Slow and Steady, Darkvision, Stone Cunning, Keen Senses, Greed, Hearty, Their Weapon Familiarity, Hatred, Defensive Traning and Stability for example.
Half Orcs have their stat bonus, Dark Vision, their Weapon Familiarity, Orc Ferocity and Orc Blood. That's it.
Gnomes have their stat block, Small, Low-Light Vision, Keen Senses, Obsessive, Illusion Resistant, Gnome Magic, Weapon Familiarity, Hatred and Defensive Training. Again that is more than the Half Orc.
All of the races seem to have more benefits. Give the brutes a break. Let them have cool ablities too.
