I am a fairly new LoL player. I have started playing League just after Volibear got released. My IGM: Black Turret. Here is my lolking profile if someone is interested: http://www.lolking.net/summoner/eune/26403602.
My first ranked games were just a pain. As you may imagine I went for ranked games just after I got 30 lvl. It didn't end up well.
Lowest elo I had was around 900. At this point I have started watching streams, mostly OddOne and Saint. I feelt in love with jungling. After some time and at the end of season 2 I was ~1300 elo. Kinda high for me :)
When season 3 started, I was playing carefully trying to do my best and after placement matches I was 1450 elo :) But at some point something went terribly wrong and I felt to ~1000. Those were bad times mostly because I stopped playing jungle, was raging a lot and playing even when not in a mood for it.
Now when season 3 started I was placed in Silver III. After a bit of games I have managed to get my self to gold IV, (almost III now :)). I know I am not the pro player or anything, but at this point I am strongly convinced that in less then 2/3 weeks I will be able to get to Plat V :).
O.K. End of talking bout me. Let's talk about Xin. I started plaing Xin at the end of season 2. He is a fun champion to play and the Husar Xin Zhao skin is just too good to not use it :D. After Season 3 started I have played almost only Xin jungle. I was playing Xin in every game I was able to jungle with him. At the best moment I had a 14 straight wins. Basically just thanks to Xin I have managed to get into Gold Division.
I do hope that after reading some of the things from this guide it will help some of you to get a higher division/leagues.
P.S. Leave me some comments, so I will know if any of those thing I said or will say were helpfull to you guys.
Best of luck to everyone, have good games and hope to meet some of you on the fields of justice :)
