Making a barbarian? Mountain dwarf or half-orc. Warlock? Half-elf is the obvious choice. Oh, wizard? You want to be a gnome or high elf.
I'd rather my players choose the race they want rather than the one a class dictates. I'm considering a house rule that allows players to change the ability-score increases from their race. The total increases and amounts would stay the same.
What are the mechanical side effects (if any) of allowing a mountain dwarf to increase her intelligence and charisma by 2 instead of strength and constitution?
Some members of my group think there would be side effects, but I do not.
