About the black Zac skin and how it cannot be a thing...
What if he had shimmery, rainbowy textures like you sometimes get with oil (since that's what he looks like to me). It would be neat to have a regular black skin with rainbows shimmering around as he moves (thus giving an opportunity for more clarity and readability).
Not that I play Zac, though, I just thought the black image looked (oil) slick.
