Introduction to Ranked Games

Ok so I've had this idea and I don't know if anyone has proposed it or not and I dont know if its already here but I'm proposing an introduction video for ranked games. Yes it sounds silly this way but I want to improve the league community and I'd like people to understand the importance of ranked games (for competitive players at least). I've been seeing to many ranked games where players didn't know what to do when their lane were pushed out or had no idea when to back etc.. That's why I'm proposing for an introduction video for ranked games so we can make them better.
