Riot, make a better tutorial with DETAILED information

There are people who come into ranked and still don't understand the basics.

They don't understand teamfighting, splitpushing, warding, objective control, purpose of things such as teleport or grevious wounds.

People don't know jack shit about this game and while it can be argued its their fault for not looking into it a huge part plays because the tutorial doesn't teach you anything but how to press buttons. They don't know much more than "This guy needs to die and that tower needs to kursplode"
