Riot Games has announced an amazingly comprehensive, well thought out system for teaching new players the rules of League of Legends. Introducing Intro Bots.
The Intro Bots are actually a small, but important new part of the tutorial system, which they have dubbed Onboarding. Mainly, Riot recognized that the game AI as it was too difficult for players to learn with. Modifications have been made to the damage dealt, as well as bot behavior, and reducing death timers.
