I guess the main thing that comes to mind that needs to be considered is that we don't know yet that that isn't what League is. There's so much we don't know, so much information we don't have, it's kinda ridiculous - but if you look at the setting (all the warring factions, the ambiguity of the Institute of War's intentions), some of the people and things we play as, some of the judgments (Riven participating in genocide, Ashram feeling threatened by Lee Sin, everything wrong with Demacia in Lux's story, etc.), and so on, we're pretty close to that kind of very dark fantasy already.
And yes, I do like that, generally speaking.
