Riot, Please oh Please add more tutorials!

Moba's are probably the most complex multiplayer game there is, simply because of the infinite tactics that exist combined with trying to play with 4 strangers. For that kind of game to have a tutorial that basically tells you nothing more than that you can items and buttons do things is ridiculous.

There shouldn't be people in ranked saying things like "oh i didnt know pink wards reveal shaco" and "Why does the 5th stack of dragon make them SO STRONG!?"

There is no point in denying that there is a huge knowledge requirement to the game, so help the players out ffs. There ought to be tutorial levels designed to teach each aspect of the game (without being 40 min long a piece) There should be:

Basic gameplay tutorial, Vision tutorial, Power spike tutorial, Item build tutorials, Objective value tutorial, Team comp tutorial, Jungling tutorial, laning tutorial, ETC ETC.

None of them should be longer than 5-10 min and they should clearly explain each aspect of the game that is REQUIRED to be successful. Lets face it, some players just simply miss certain key aspects of the game and by 30 they are torturing other players because they say things like "why would i ward when i can spend my gold on damage"

I wouldn't even be opposed to restricting players from ranked until they complete all the tutorials and actually understand the elements of the game.
