Too much of something is a bad thing....too much void and you running around with tentacles talking 10,000 words a minute, too much light you get homicidal zealots like the scarlet crusade, beings like X'era who tried to force light on to Illidan and now this, without the balance of void and light alt dreanor has become a living hell....its a warning for us on main Azeroth...we can only trust us and maybe Elune.
