Cool idea to help teach beginners

Just, some form of campaign. It hardly needs a story line (although that would be awesome.) What I mean is just like teaching people who just finished tutorial so they know how to play the game, but not how to win (if that makes any sense.) You could have like 9 practice sessions of really basic topics like farming, objectives, roles, itemization, draft/ blind pick etiquette, Skillshots, actives on items, use of cc, and finally identifying play-style. Finishing each one would give you good xp, if not a full level and at the end give you a cheap champion that fits your play-style. I think that starting with this would help deal with smurfs getting mad at players for not knowing the "basics," which they have no reason for knowing. This could also help deal with the people who leave early due to the incredibly painful task of figuring out your play-style

tldr: Method of learning the basics and how you naturally play
