I wonder how much this argument would have changed (or changed at all), if Tasha's had instituted a three-point system. What if:
Your Origin gives you a +1 to any stat of your choice
Your Background gives you a +1 to a fixed ability score (Adept = +1 Int, Acolyte = +1 Wis, Athlete = +1 Con, etc.)
Your Class gives you a +1 to the key ability score (Bard = +1 Cha, Cleric = +1 Wis, Fighter = +1 Str or +1 Dex, etc.)
Would this have solved this ability score issue, in your opinion, by spreading them out across the character build instead of concentrating them on "race" alone? Or do you think it would it have only exacerbated the problem, creating an incentive for players to cherry-pick all the options just to get an all-important +3 to Whatever?
