Where have the grand-scale league animations gone?

I've been playing league since the end of s3 - and in all this time my favorite league interactions was watching the game I loved portrayed in epic, beautiful and exciting animations. Ever since I watched 'A Twist of Fate' I was mesmerized by the detail and action the video portrayed. Thankfully, however, this was not a singular encounter, as I would soon watch and re-watch (they're all so good >.<) the subsequent yearly releases - 'Get Jinxed!', 'A New Dawn' 'Seconds' and finally 'Project: Overdrive'. Sadly, however, that was the end of the insights into the gritty, beautiful world of League Riot has since offered in the form of animations; With all due respect to the many other animations that have been released, (skin videos, story videos) of which comprised as being cute, entertaining, illuminating, or soul-wrenching (looking at you The Curse of the Sad Mummy), nothing has since captured the art of showing a realistic Runeterra for what it truly is; A land wrought with war, violence and destruction, permeated with champions who fight in a death stadium for good, evil, county, entertainment, or mostly something in between. It has been nearly a year, and although Overdrive was beautiful it wasn't the same as its predecessors, more specifically Twist of Fate and New Dawn. I'm curious to know if more of these grand videos is something Riot intends to work on or is in the process of working on. Animations of this scale do not happen overnight but as the average consumer of this wonderful game I have but a single passion burning inside me - I want to see more! (A movie centered around the ninja's of runeterra would be most delightful). Also will there be any update to the lore behind (Not-Summoner's but still) Summoner's Rift?

TL;DR Moar Epic Videos Plox!
