So why not just give it a little bump and create something with it's own niche, instead of making a +2/+1 vehicle like the other races. Give it a free skill or tool proficiency, or a once a day power.
Sample
Determination: Add d4 to one attack role, skill check, or saving throw that you failed. Once you use this you may not use it again until after a long rest.
Right, this human is more versatile. Getting to put that plus 2 wherever you want is very valuable, which balances the half-elf's extra skill, darkvision, conditional saving throw advantage, and extra language. The half-elf is only "better" in Charisma primary classes.So, again, not using Tasha's. So the Half-elf would probably still dominate for at least bard, warlock and sorcerer. Though even here, human is not that far off. Maybe thats OK?
Looking for a human alternate.
If you roll abilities it is more powerful than it is with point buy.Standard human is OK, and I have had some. But, many here on these boards would tell you that its under-powered.
Only if you roll stats IMO. If you use point buy or standard array the points are fungible and the only way the +2 charisma doesn't help is if you want to dump Charisma.Right, this human is more versatile.
