Two things. First taking a feat from Variant Humans and giving them a skill is hardly a fair trade. Second I think Larian are going to want to encourage us to take an origin character in the main game so it's unlikely they'll be giving out feats to custom characters so as to discourage this.
Thats not what I said, what I said was... give regular human an extra skill, and not have variant human at all.
And I think the major detractors here are al missing one major point I made... which would be fixed by reading my original point. The character creation is already missing majorly powerful aspects, such as tool proficiencies, and the background features, and the languages.
The games character creation already lacks a majorly powerful component, and there is no feasible way of integrating those components because they are more roleplay based.
Including a feat for level 1 custom player characters is the only way I can see to bring them up to par with a 5e character, and with the starter origin characters who all get free goodies anyway.
