I was writing a longer answer to this thread, but it got deleted and maybe it was for the better. I must say in all honesty that I think this is an utterly ridiculous idea. I think that you Free, should use your enthusiasm and creativity on something outside of this game.
Firstly, I don't understand your use of the word Pro. What is and who are the "Pro" players of WA? Are you a pro? It's a wording I don't think belong to this game or community. Secondly, why would anyone invest their time in watching how newbies learn how to play this game at all? It's beyond my imagination, and I can't believe someone would use their sparetime to watch how newbies learn the way to play an odd game through streams, games, youtube channels and what not. I think you're living in a bubble Free, and you have to get out of it.
You're talking about this big audience, awesome promotion videos, streaming channels and what not, but I'll say it straight out because you need to hear it: nobody would give a big f@#! about it. I can give you credit for your good intentions and belief, but you really have to get your head out of your arsehole Free. This is a horrible idea.
Why do we play computer games? Besides having a bit of fun, it's about exploring the game, expanding your knowledge of the game, and creating relationship with people from all over the world. This is something that you have to do on your own. You shouldn't be taught by others on how to do it, it just doesn't make any sence to me. It's the whole fun of playing the game.
