Whenever you find a new champion that you want to play, make sure you google "Champions name here build guide"
I like mobafire guides, but solomid guides are good also. :p
Occa, I'd like you to prove that you're a diamond. A lot of people say they are, but they really aren't.
I'm friends with a lot of diamonds, I play with diamonds every day because of that. I've gotten a lot better but i'm stuck in my elo, not because the people in my elo are necessarily bad. But they aren't used to the diamond mechanics that I try to use.
Moral of what I'm saying... I got paired with people that aren't at my skill level because right when I got level 30. I went and did ranked, which was a huge mistake. I got put into silver because I threw games. (I was a noooooooooooooooooob back then)
I can't repeat this to my friends that just started playing league. Make sure when you get level 30, only play ranked when you feel you're ready. Or else you'll regret it.
