It just makes some races universally better. Before you could rate races based on classes and vice versa, now they are just universal.
S tier - Elves, Half orcs
A tier - Dwarves, Tieflings, Half Elves, Gnomes
B tier - Githyanki, Halflings
C tier - Dragonborn (not F only cause they look cooler)
F tier - Humans
Tasha also did not remove stat points from Half Elves and Shield Dwarves and you could run Variant Human instead of whatever Larian made. And even using Tasha's Cauldron of Everything, the Dragonborn were considered weakm which is why others attempted to buff them in various ways, such as giving them Darkvision (which made Lore sense, given that Dragons have it), buffing Breath attack and giving them more features.
