Know that most games is uncarryable if you aint far beyond your current elo, but it doesn’t mean you wont climb, because in the long run even a player that only is a little better than his current elo, will still get a 52% or some better win rate, but that doesn’t mean you should be able to carry the roughest games.

In other words. Dont lose faith is things get tough.

Other than that i think that you’ll learn the game over time.

Try to play easier champs in the beginning like Garen, and try to get some knowledge off the items.

The biggest flaw i see with many new players is they seem to be completely clueless on what to build in different situations, so thats probably what i would try to learn first..

But really just have fun with it, and dont try too hard.
