Prestige Editions were supposed to be these rare and exclusive skins that you could earn, they weren't supposed to be just a simple recolor/chroma, they would actually have visual differences to set them apart from the original skin that they're based off of, but no matter how you look at it Blood Moon Aatrox Prestige Edition is just a glorified golden chroma. K/DA Kai'Sa Prestige Edition and K/DA Akali Prestige Edition have altered appearances to their original counterpart to set them apart from each other. The Prestige Editions are much flashier looking than the original skin in both the character model and the splash art, and you also get a loading screen border with the Prestige Edition as well.
One quick look at Blood Moon Aatrox Prestige Edition will show you that there is no visual difference at all other than the color of the skin. The Prestige Edition is just a gold recolor of the original, there is no other difference design wise at all. Not only that, the splash art as well is the exact same, it just looks like they added a gold filter over it. There is also no loading screen border for the Prestige Edition either. Another thing to add as well is that the Prestige Editions kind of lose their exclusivity if they're going to be released back to back like this. Way more time should be given before releasing another one, they shouldn't be released one patch after another.
I hope changes are made to the skin before they are released. It's a cool looking skin, but most people agree that the original skin looks far better than the Prestige Edition. There is nothing "Prestige" looking about this skin, it's just a golden chroma that is being passed off as a Prestige Edition skin. This is only the third Prestige Edition skin and they're already getting lazy with it.
TL;DR Blood Moon Aatrox Prestige Edition is just a glorified golden chroma being passed off as a Prestige Edition skin.
