Any Team willing to teach a Semi-Noobie?

Hiya All. I don't really know much about the game at all. I'm Lv. 18 and mostly played COOP vs A.I and a couple normal games. Don't know much about the advanced stuff about the game and really want to learn how to play the game. Along with wanting to learn I mainly want to make some friends along the way since I'm playing by myself 100% of the time. As for a champion I don't even know which one I really like to main I know there are a couple that I enjoy but nothing yet in stone yet. If any team or anyone is willing to teach me that'd be awesome and hopefully we can become friends along the way. :)

Thanks & GLHF
