I want the Reaper skin that we have been seeing all over the internet. You know, the pink maid one that's been floating around.

I think if Blizzard catches enough wind of it and many people actually press the skin, we might actually see this skin in the future of Overwatch somewhere down the line.

Everyone has been had mixed feeling about the said skin but I feel that it would just be a great addition to the game. Just to witness the unexpected feeling of a Reaper ult in a cloud of pink mist and Sakura blossom petals would be something that brings the game a lot of joy just from the sheer surrealism that it would bring.
For anyone still wondering about the skin in question, you can see it here in a few fan made animations.
