Yes i'm suggesting that fallout 4 has classes and if not it SHOULD.
Here i will list some of my ideas:
Super Mutant:
strength bonus and endurance
Ghoul:
rad. ressitance and survival bonus
Human:
speech bonus and barter bonus
cyborg:
int. bonus and science
vault dweller:
wealth bonus and luck
alien:
science and energy weapons
those are just some ideas.
