Shadowfire Diana
Okay, this is just me, but does anyone else think that this skin would be amazing? It fits the theme of her character, and the theme of Team Fire winning All-Stars. I think they could make some great particle animations between her Orbs/Shield and her Q, even her E could have, lets say, a burst of shadowy flames ignite the ground for a moment. But again, I just thought that would be cool, I don't know about the rest of you.
