Well league doesn't have the best community so my only tip for you is keep playing and ignore all the hateful things people will say to you just keep practicing

I suggest watching educational streamers in the roles you enjoy playing, for me it's ADC and JG so I watch [url=twitch.tv/imaqtpie]Imaqtpie[/url], he was an ex pro player ADC main who started streaming because it pays more. Then there is [ Register or Signin to view external links. ] , a high elo Jungler who is known for his rengar.

Saying league doesn't have the best community is the understatement of the century. It's easily the worst community I've ever seen in game history. If I can have a couple of games in a row without people telling me to kill myself or get cancer its a miracle. I would suggest finding friends who play the game too so they can teach you, and only play with groups until your comfortable. Mute randomers. Learn a select few champions and roles and watch youtubers beginner guides. Don't bother watching any streamers or high elo (ranked) players because all they will do is teach you things you barely understand or that are irrelevant to newer players.

A couple of small things I would recommend is learning how each champion builds item-wise and only really building the core items. Learn map awareness and playing with the camera unlocked. Learn how each champions unique abilities work (which comes with playing more games), and playing ARAM probably helps quite a bit since its a lot more casual, with more variety of champions and constant teamfighting which is important in normal games anyway. How to cs and what position to be in and when to be in it, but a lot of that comes with time. Learning things like vision is pretty irrelevant for beginners and you'll eventually just pick it up.
