This has been a recurring complaint since EA. In terms of gameplay, the design exists so that your stats matter - otherwise everyone would dump CHA. In terms of narrative, it's because you're the designated party leader. You've brought everyone so far despite your 10 CHA and thanks to your 20 INT. Leadership is more than just magnetism, and the role certainly cannot be delegated to a non-character just because his character sheet says he has a higher CHA score.
