I think he/she meant more along the lines of say, your character having a missing arm or leg, or having some sort of deformity. I think this would be a nice little add on, but since deformities are a little on the rare side it probably wouldn't be implemented. I like the idea though :D
Well, this actually is an interesting idea. Though, like Warrior stated before me, the option of deformity probably won't be added due to the fact it's quite rare and if it was to be added, well then most individuals would probably want to use it. However, a nice touch and full of creativity your idea was. I like it.
