Okay! Akali and Yasuo have enough skins now! Someone else can have a turn! Akali just got a project skin and Yasuo just got a arcade skin they don't need anymore!!! Maybe like Karthas? Vel'koz? Gragas? Zac? Elise? Syndra? Sejuani? Skarner??
They all pale in comparison to the popularity of Yasuo, Ezreal, Lux, etc.
I don't like it either, but that's just how businesses work. Why would Riot put effort in to make a good skin for Ornn and the hundred thousand people who would buy it (if that) when they can sell upwards of a million for champions like Yasuo, Akali, Ezreal, and the other popular ones?
Also, obligatory mention, this skinline (True Damage) was inspired by, designed by, and created with the help of Louis Vuitton. It's in both Riot's and Louis Vuitton's best interest to make as much money as possible from it, and the only way that would happen is if the skins went to some of the best sellers. I don't think True Damage Ornn would fit, anyway.
