Completely missing the point. I'm not saying every race should be "can do a bit of everything." I'm saying that every race that is capable of being a player character should have sapience, self-determination, and personal identity. Sapience being human-like awareness and intelligence: the ability to understand oneself as distinct from one's environment, to reason about the world around oneself, etc. Every playable species should have this trait in order to be, y'know, playable. Self-determination should, I hope, be self-evident, but just in case, it means the ability to make one's own choices for how one will live, what actions one will take, etc. (Obviously, some situations like dictatorial regimes or slavery or the like can severely degrade a person's ability to exercise their self-determination, but they have said determination nonetheless.) And, finally, a personal identity is individuation: all the personality quirks, verbal tics, tastes, preferences, dislikes, turns of phrase, etc. which make a person distinct from other people.
