It most certainly benefits min maxers just as much as role players because now not only can they maximize their ability scores, they can maximize racial skills/abilities.
Ah. Fair point. I had thought with the perspective of someone primarily interested in roleplay/stories (yet with an eye for a minimum power-gaming). Being not an expert power-gamer or a minmaxer, I didn't immediately think of racial traits. I thought : if you're a minmaxer and don't really care about who you play, race is essentially just giving you a set of ASI. But it also gives racial traits (skills, unique abilities, etc). So Custom Origins benefits minmaxers more than what I thought. Well, then Custom Origins probably benefits both roleplay-first players and minmaxing-first players.
Oh absolutely, once I saw that D&D is likely to make Tasha's the only official way going forward to assign ASI, I just looked for the most potent combination of racial spells and additional effects.
Mostly it revolves around races with Misty Step (or similar) at Level 1. That is a very very strong ability.
