I said this year's ago with many others.
Riot nowadays is no longer a patriotic company based in the USA. Notice we haven't had July 4th skins in like forever but we had the Chinese lunar festival ones. Since they are owned by tencent.
There is also the "excuse" that they wouldn't sell because it is an American only sport. Semi believable, poorer countries can't afford the helmets and shoulder pads like they can a simple soccer ball. Plus the "barbaric" nature of the game is rarely matched.
I wanted some so bad before, yet riot never made em. To be honest even if they did I wouldn't buy em since I'm on a pretty sincere boycott do to things they been doing.
