Riot promotes Communism!!
I discovered something today.. League of Legends promotes communism!
So the company that owns like 40% of Riot is Tencent and it is a Chinese based company
So now imagine if China was Demacia and the US was Noxus
Demacia is a communist monarchy- it is ruled by a monarch (technically Jarvan III but Jarvan IV in lieu while he is sick) and it promotes the idea that you cannot succeed in Demacia unless you are born into it, it may not say it but its implied. Nearly all Demacian champions are noble (bar a few exceptions like Xin and Shyv who was adopted into the noble family)
Noxus is a "tyrannical" republic - It is ruled by Swain and his counsel but Swain is still looked at as a "tyrant" (just like a lot of US citizens look at the president) they promote the idea that ANYONE can succeed as long as they have the ambition to do so. Very few champs from Noxus are actually nobles and some of the most important ones had humble beginnings: Darius, Draven, Vlad, Singed and Riven(before she went good)
So there you go Noxus the "bad guys" are really the US and Demacia the "good guys" is really China
