I Want it Livestreamed in HD

No, you happen to watch the video from a Zero POV. I don't know since when particular content, but they've added unique dialogue for all classes.

 Spoiler

The transaltions by Edan arent too clear, but the Black Mage did say that he needed another transcendant to face him and defeat him, that other transcendants would simply accept their destiny while he knew the player wouldnt. IF you take in the fact that the player is manipulating Erda for the 5th job skills and even the desires of the world, sounds like he could really be a transcendant from a story point of view.

So what the Black Mage meant with "Ultimate light found in ultimate darkness" actually refered to throwing the whole world into chaos to raise someone strong enough to kill him and free him of his eternity? Well i guess thats a good argument for the villain of the story
