If we really want to delve into this matter of trying to find a realistic balance between our characters then we should discuss what is or isn't possible in say a Rogedyn vs Lalafell (I'm sure I misspelled both of those.) because let's face it, a midget warrior who doesn't barely come to the shins of his opponent is not going to beat him. Their swords are the equivalent to a small pocket-knife, and their bows, given their small sizes would not hardly be capable of a killshot, much less even penetrating basic armor.
