I agree with quite a bit of this, but Dwarves should not get +2 AC. IMO Gold Dwarves should get Light Armor Proficiency and Shield Dwarves should get one Armor Proficiency better than that granted for their Class (minimum Medium Armor + Shield); if they get Medium Armor from their Class, they get Heavy Armor instead and if they get Heavy Armor Proficiency for their Class, they get Heavy Armor Mastery instead. [...]
I dont think thats really possible.
For example if you start your Shield Dwarf as Bard, would you later get Heavy Armor Proficiency when they pick College of Valor or College of Swords ?
What about starting as Bard and later taking a level of Cleric with one of the many domains with Heavy Armor ? Would they then get Heavy Armor Mastery ?
I would say +2 AC is much easier to implement.
