The problem with tutorials that say things like "the jungle and solo start at the yellow buff" or "the support should stay in the duo lane until around level 5, when they rotate to help the mid lane" is that:

1.) That's information fucking overload for a new player. What are they supposed to do, get out a note pad? Is there going to be a quiz afterward? Almost nobody that's been playing this game for all of 30 minutes is going to give enough of a fuck to pay attention to all that shit, they're just going to say "fuck that" and either exit the game or go back to arena where they don't have to make some fucking flash cards to play properly. I mean a bunch of them are probably still trying to wrap their head around what to build..

2.) They enforce a meta. They're like a really shitty high school math teacher that says you HAVE to use their algorithm for this type of problem or else you're wrong. Conquest might have evolved to be the game mode where everyone has to start like this and you have to rotate here and if you win the team fight you have to get gold fury, but that's actually not a core part of conquest, that's just the optimal way to play it as dictated by pro players and theory crafters. That's why they call it the metagame- it's not the game, it's the game the players make themselves to play the game more optimally. So by its very nature it's changing constantly because it's not even a real part of the game. And if somebody decides that putting 3 people in mid lane is actually the optimal then more fucking power to them. But if an in-game tutorial tried to cram all that information in your head- now it's not a metagame, it's a regular game. Let people think outside of the box, even if it's kind of stupid. That's how you get the meta in the first place, trying shit out.
