I dont know how to play this :/

Someone can help me on how to play lol? im new to this game and im soo noob ;/ trying to get rankeds on :D

that doesn't really make sense. You can't play ranked if you're new to the game, you need to be level 30. The game puts you through a tutorial so that's the best way to start, you should just play co-op until you get a decent understanding of the game and then move onto normals. After you've reached the point of understanding the games basics you should watch LS' coaching videos. That's probably the way I'd do it if I was going to teach a friend of mine how to go from complete beginner to decent the most efficient way.

its not that hard just watch some yt vids you will get the hang of it pretty quickly

Play ADC. It's generally the easiest lane to play for newbies. Just take Ashe/Miss Fortune and you should be good to go. Just remember to farm appropriately.

Thats suck. Maybe watch tutorials/tips on youtube.
