LF mentor or some cool people to play with

Hey there forums. Have been playing for about two weeks now. My friends from where I live got me into the game, but due to my work schedule, it's hard to play with them. Also they're more concerned about their ranked games than playing with their scrub of a friend.

It would be awesome if someone could give me a few pointers on my play and help me improve. I'm really liking Supp because I'm not one to like being the main damage dealing person on the team. Contradictory to that though, I do also playing ADC if it's open. Not that interested in jungling since at level 14, I don't have the runes to do it.

At the same time if just some cool people want to just play normals until I get to 30, that would be awesome too.
