I will not allow for their to be assist type characters that are playable. Link should one man army because it is a video game and therefore realism does not and should not apply. It is also the story of a specific hero who defeats a villain as a part of his greater destiny, not of some weakling who needs help from other people (other than getting items and the other minor forms of assistance Link receives). I think cutting back on the hero's ability would make him lame.
