I think Larians decision to give everyone +2/+1 on attributes instead of following the PHB rules is a huge improvement and allows everyone to freely pick their prefered race and class combination without feeling gimped in regards to stats.

However the races need to be rebalanced for this afterwards, i.e. the extras must each add about the same amount of power to the character.

My suggestions would be something like:

- Change Human to : 1 extra feat, 1 extra skill, 1 extra weapon proficiency

- Change Half-Elf to : 1 extra skill, 1 extra weapon proficiency, advantage vs charm, darkvision, subrace features (as before)

- Change Gold Dwarf to: As before, plus +50% carrying capacity

- Change Shield Dwarf to : As before, but instead of medium armor proficiency: +2 armor class (stacks with anything), +50% carrying capacity

- Change all Dragonborn subraces to : Resistance against Elemental Damage Type, 1/day Breath Weapon 17ft cone, 1d6 Elemental Damage Type damage; level 5: 2d6 damage, level 10: 3d6 damage, and maybe an indiviual 1/day or 3/day spell, or a cantrip, for more flavor and more differences between the subraces (many of which are now exactly the same as another choice, if they both go for the same elemental damage)

Reasoning:

I find extra carrying capacity a typical dwarven thing. They are short and broad and endurant, thus they can carry more. Also, they are kind of greedy and/or materialistic, which also fits the pattern of wanting to carry more. Why on the other hand humans should have such a property is a complete mystery to me.

Shield Dwarf are supposed to be a warrior race and need a racial ability that does NOT motivate everyone to exclusively only play Shield Dwarven Sorcerers and Wizards and nothing else, ever.

Humans are supposed to be the flexible race that can do anything. An extra feat and skill should do that. Random armor, shield and weapon proficiencies plus extra carrying capacity not so much.

Half-Elves are supposed to be a mix of human flexibility and elven grace, and thus get adjusted for the changed definition of human. They do however need to sleep and thus shouldnt be immune to magical sleep.

Giving Humans and Half-Elf an extra weapon proficiency allows Shadowheart to still use Spears. Alternatively, Clerics could sunoky get extra weapon proficiencies depending upon their choice of deity. Assuming they dont pick Tempest or War.

Dragonborn are clearly inferior to Tieflings in their racials.

Alternative ideas: Shield Dwarf could instead of 2 extra armor class simply get 2 damage reduction against all physical damage
