You know, that could be a funny little feature, but I don't see how it would/could change the gameplay. The way I see it is it'd just be flavour text which 60%+ of the userbase will completely ignore. If the traits actually did add some bonus/disadvantage (i.e. Eagle Eye = +10% Crit Chance, Numb Hands = -20% Base Damage), it would probably break the balance of the game completely. Unless they're very, very small and barely noticeable differences. Still a fun idea though.
