I'm almost speechless at this moment, when I'm trying to figure out a response to your idiotic post.
Your first sentence completely ignores my premise that "backstory and lore are not the same" and yet you try to say: "Because of the way champions are linked together in story, very few of them would have back stories that don't interact with anyone. Hence, they are the same thing."
IMO you are making a pretty huge nonsensical logic jump here that doesn't really make sense. I just don't get what you're trying to say.
Champion's have always had loose connections with one another through storytelling...I never tried to dispute that.
I also disagree with you when you say "Lore has nothing to do with Runeterra, that is something you are attributing to it that has never been stated. Lore is about the champion."
When we talk about lore, we are talking about worlds as a whole, not just single individuals within those worlds. In this case, you are just plain wrong.
