Skeletor was so cool in ED.

Hell, Super Metroid got voice acting right.
To give Link substantial voice work would pull him away from being the quiet humble hero we're used to. Or if he had voice work, he wouldn't talk much at all, since everyone else in the game barks orders and requests at him.
Well, what do we gain from Link's voice acting? Do we get to hear him think? Will he be a humble, boring guy to listen to? Will he have an annoying attitude? Or will he be horrendously witty like Reon S. Kennedy? Is there anything profound going on in his head other than "how the fark did i get in this mess? oh yeah, it was that &$*^$#*@ princess!"
Frankly, I don't care what he thinks. They'd have to go thru the trouble of making up some motivation and conviction for him, and he'll probably angst out like Lloyd from Tales.
Wind Waker's Link told plenty through his fat face alone, and I was satisfied.
