I guess that's kind of the point. Keep it within the known, yet remove the obvious goblin-favor for melee-oriented characters or elf for the magical ones. I'm not claiming it's perfect since it would enable hobbits to be as strong as goblins, but it will remove the need for everyone to be goblin in order to have a fighting chance.
Ah, the numbers.. Could of course be substituted with some kind of written levels.
"You've chosen to focus all/heavily/somewhat heavily on physicals"
or
"You've chosen to focus primarily on strength and secondary on dexterity and constitution"
Another option (yet more limiting) could be to make selectable class-like setups
Barbarian: Mostly strength, secondary dex/con
Warrior: Purely physicals
Knight: Mostly physicals, some mentals
Rogue: Mostly dex, some mentals
Caster: Purely mentals
choose warrior
"You've chosen to live the life of a warrior"
I don't know Gorbie, every system has its ups and downs. It's a suggestion. Take it, leave it, use some, leave some out or flip me the finger. I guess I'd like to see human fighters who can fight. No orc (elf soul) mages, or otherwise casters with pointy ears etc.
