Here's something Riot doesn't seem to understand.

Besides the Summoners, the Fields of Justice and the Institute of War, your lore is meh. Simply meh. There are little to no original ideas in it, it's mostly cliché after cliché after cliché. There was a time when you were all about subverting clichés. In those times, perhaps Riven was a secret disciple to Yasuo's master, and she murdered him because he was going to sell out the temple to Noxus. But those times are past.
Tell me, what's unique about Frejlord? Demacia? Noxus? Noble-Warrior-Race-land, Typical-Honor-Before-Reason country, and ******bag-City, with a taste of Social Darwinism. Piltover's punk city, making it every city in every steampunk setting ever. Zaun's "THE DANGERZZ OF TECHNOLOGY GUYZZ!!1!1!" without any proper positive given to them besides "In it Zac was born". The only unique nation is Bandle City, home of the Yordles, who by themselves are every dwarf cliché combined into one furry package.
You know what made this tasteless, paper-maché disgrace of a story worth a damn? The Institute of War, and the unique social-political consequences it brought. It is such a good, interesting idea, with so much to explore in it. But now? Why would we care what happens in this game? Why should we care about bland, unoriginal city-states and the people which they represent?
This is a huge mistake, one which will destroy the already-diminished lore fanbase you had. You took a great, unique feature on your game (Lore which, unlike DotA2, was actually cool, interesting, and worth a damn) and took one giant dump in it. So congratulations Riot, for ruining your own work.
